Expose cljs.core/Cons in SCI config (#142)

This allows (instance? cljs.core/Cons x) to work in Scittle code.

The Cons type exists in the compiled ClojureScript runtime but was not
exposed by name in SCI's symbol table. Libraries like Trove need this
for type checking in their const-form? function.

 # Dev
 
+## Workflow
+
+### Start with an issue before writing code
+
+Before writing any code, please create an issue first that describes the problem
+you are trying to solve with alternatives that you have considered. A little bit
+of prior communication can save a lot of time on coding. Keep the problem as
+small as possible. If there are two problems, make two issues. We discuss the
+issue and if we reach an agreement on the approach, it's time to move on to a
+PR.
+
+### Follow up with a pull request
+
+Post a corresponding PR with the smallest change possible to address the
+issue. Then we discuss the PR, make changes as needed and if we reach an
+agreement, the PR will be merged.
+
+<!-- ### Tests -->
+
+<!-- Each bug fix, change or new feature should be tested well to prevent future -->
+<!-- regressions. -->
+
+### Force-push
+
+Please do not use `git push --force` on your PR branch for the following
+reasons:
+
+- It makes it more difficult for others to contribute to your branch if needed.
+- It makes it harder to review incremental commits.
+- Links (in e.g. e-mails and notifications) go stale and you're confronted with:
+  this code isn't here anymore, when clicking on them.
+- CircleCI doesn't play well with it: it might try to fetch a commit which
+  doesn't exist anymore.
+- Your PR will be squashed anyway.
+

+# Loading JS libraries
+
+Since `v0.7.28` scittle allows to load libraries from the global enviroment.
+This means you can load a library in a `<script>` tag and use it via `:require` in scittle.
+
+An example:
+
+``` html
+<html>
+  <head>
+    <script src="https://cdn.jsdelivr.net/npm/scittle@0.7.28/dist/scittle.js" type="application/javascript"></script>
+    <script src="https://cdn.jsdelivr.net/npm/js-confetti@latest/dist/js-confetti.browser.js"></script>
+    <script type="application/x-scittle">
+      (require '["JSConfetti" :as confetti])
+      (.addConfetti (confetti.))
+    </script>
+  </head>
+  <body>
+  </body>
+</html>
+```
+
+## ES modules
+
+The async nature of ES modules makes them a litte bit more difficult to work
+with in scittle. You need to disable automatic evaluation of script tags first
+using `scittle.core.disable_auto_eval()`.  In a `module` type `<script>` tag you
+can then load ES modules, attach them to the global object and manually invoke
+`scittle.core.eval_script_tags();` when setup is completed.
+
+``` html
+<html>
+  <head>
+    <script src="https://cdn.jsdelivr.net/npm/scittle@0.7.28/dist/scittle.js" type="application/javascript"></script>
+    <script>scittle.core.disable_auto_eval()</script>
+    <script type="module">
+      import confetti from "https://esm.sh/canvas-confetti@1.6.0"
+      globalThis.JSConfetti = confetti;
+      scittle.core.eval_script_tags();
+    </script>
+    <script type="application/x-scittle">

+# nREPL
+
+To connect to a Scittle nREPL server from your editor, follow these steps. The
+setup described here, can be found in this directory.
+
+In babashka or Clojure JVM, use the
+[sci.nrepl](https://github.com/babashka/sci.nrepl) dependency and run:
+
+``` clojure
+(require '[sci.nrepl.browser-server :as nrepl])
+(nrepl/start! {:nrepl-port 1339 :websocket-port 1340})
+```
+
+This will run an nREPL server on port 1339 and a websocket server on port 1340.
+Your editor's nREPL client will connect to port 1339 and your browser, running
+scittle, will connect to port 1340. The nREPL server forwards messages to the
+browser via the websocket connection.
+
+In your scittle website, you will need to include the following, in addition to
+the normal routine:
+
+``` html
+<script>var SCITTLE_NREPL_WEBSOCKET_PORT = 1340;</script>
+<script src="https://cdn.jsdelivr.net/npm/scittle@0.7.28/dist/scittle.nrepl.js" type="application/javascript"></script>
+```
+
+Also include the CLJS file that you want to evaluate with nREPL:
+
+``` html
+<script src="playground.cljs" type="application/x-scittle"></script>
+```
+
+Then visit `playground.cljs` in your editor and connect to the nREPL server,
+and start evaluating!
+
+See the `index.html` file for an example.
+
+When you run `bb dev` in this directory, and then open `http://localhost:1341`
+you should be able evaluate expressions in `playground.cljs`. See a demo
+[here](https://twitter.com/borkdude/status/1526285565343281159).
+
+Note that the nREPL server connection stays alive even after the browser window
+refreshes.
+
+### Custom host address
+
+By default, the browser will connect to a websocket on the same host as it is loaded
+from, using `window.location.hostname`. If you need something else you can specify
+that setting the window variable `SCITTLE_NREPL_WEBSOCKET_HOST` like so:
+
+``` html
+<script>var SCITTLE_NREPL_WEBSOCKET_HOST = 'localhost';</script>
+```
+
+### CIDER
+
+Choose `cider-connect-cljs`, select port `1339`, followed by the `nbb` REPL
+type.  If you use multiple REPLs in your project, choose
+`sesman-link-with-buffer` to choose the right REPL for the right buffer.

+# Scittle in a service worker
+
+You can use Scittle to bootstrap a ClojureScript based service worker.
+
+Put the following code into e.g. `scittle-sw.js` to create a JavaScript based service worker, load Scittle, then fetch your script and eval it.
+
+```javascript
+importScripts("scittle.min.js");
+
+const request = await fetch("sw.cljs");
+const text = await request.text();
+const result = scittle.core.eval_string(text);
+```
+
+Then load `scittle-sw.js` in your HTML:
+
+```html
+<script>
+  if('serviceWorker' in navigator)
+    navigator.serviceWorker.register('scittle-sw.js');
+</script>
+```
+
+This will load `sw.cljs` and eval it in the context of the service worker.
+
+A ready-made example can be found at [chr15m/scittle-template-serviceworker](https://github.com/chr15m/scittle-template-serviceworker).

+# Demo
+
+A demo project of a custom scittle build.
+
+This demo project uses the `scittle.javelin` and `scittle.hoplon` plugins which aren't part of the normal scittle distribution.
+
+To produce release `.js` files, run: `bb release`.
+
+See:
+
+- `bb.edn` with
+  - `:deps` which includes:
+    - a dependency on the `scittle.build` project to build scittle + custom features
+    - zero or more plugin dependencies
+    - helpers like static file server
+  - development `:tasks`. Run `bb dev` for development and `bb release` to produce release artifacts.
+- `deps.edn`: this only contains a dependency on scittle itself
+
+Available plugins are in the `plugins` directory inside the top level directory of this repo.
+
+Writing a plugin involves writing
+
+- SCI configuration (this can be shared via the [sci.configs](https://github.com/babashka/sci.configs) project too)
+- Adding a `scittle_plugin.edn` file on the plugin's classpath (e.g. in the `src` directory). This EDN file contains:
+  - `:name`, name of the plugin
+  - `:namespaces`: the namespaces exposed to SCI
+  - `:js`: the name of the produced `.js` module file
+  - `:shadow-config`: the shadow-cljs configuration specific to this plugin
+- A `.cljs` file with an `init` function which calls `scittle/register-plugin!`.
