Compiler warnings that need to be dealt with

[comamitc]

These are largely due to things from clojure that aren't exposed or suitable for clojurescript. There are some weird instances where rewrite-cljs can't find methods within it self but these might be from compilation issues further up the chain.

[comamitc]

There are many large differences in rewrite-cljs but thinking about issuing a PR to it to clean it up and make the port as minimal as possible.

import-vars is the one of the main things missing:

The last 4 errors above are present on the parent library rewrite-cljs. I will open up an issue for those at a later date. (or submit a PR)
