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.

+# 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">
+      (require '["JSConfetti" :as confetti])
+      (confetti)
+    </script>
+  </head>
+  <body>
+  </body>
+</html>
+```

+# 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!`.
