Support running tests for ClojureScript files

[heralden]

:RunTests runs the Clojure tests for the namespace when invoked from a .cljs file, and cpr only does a :Require.

Any chance of adding support for cljs.test? It seems it can be a bit tricky with s:capture_test_run as it uses many clojure.test functions that aren't present in cljs.test.

I'm open to ideas.

It's probably still missing some cases, but I've been working with this for some time: https://github.com/dhleong/vim-hearth/blob/master/autoload/hearth/test/cljs.vim

As far as cpr goes, I think part of the problem is that vim-fireplace tries to call load-file on a resource path, but it expects an actual file path. So, while the src/test is on the classpath, using (load-file "foo/some-test.cljs") on src/test/foo/some-test.cljs will not work anyway - it needs to call (load-file "src/test/foo/some-test.cljs").

Also worth noting that shadow-cljs added support for relative paths fairly recently.
