Icon extensions

This issue proposes the ability for extensions to provide custom file and folder icons in Zed.

We should definitely do this soon, since our initial use case for extensions is going to be adding support for custom languages. Do you want to propose a precise schema by which extensions could define file icons?

Would it be reasonable to look for an icons directory in the schema?

I'd love to have material icons in zed :) Upvoted.

would it be fair to let users create a file-icons directory and then associate each file as a string key with the corresponding extensions as a value of list of strings?

Yeah, this seems like it'd be fine.
