Embedding cherry in an existing CLJS app for runtime eval

Question:
@borkdude Will a plugin system be necessary (or, if not, at least sensible) for a possible future Cherry-Scittle?

Explanation:
With every new Scittle release, libraries (like Reagent) are specifically built and shipped with the release bundle as a plugin. Old plugins cease to work. Users need to ship their own Scittle version if they want to provide some strange feature.

It would be a huge improvement if users could build own Cherry-Scittle libraries on top of the official ones.
