Fixed rest of compile-time warnings

Hey,

I fixed rest of the warnings. Now I need a close review, as I might actually broke something with this PR (though I hope I didn't).

There is one more message left, it is about redefinition of `clj->js`, which happens in dependency library fetch.

```WARNING: clj->js already refers to: /clj->js being replaced by: fetch.util/clj->js at line 3 deploy/core/node_modules/lighttable/cljs/fetch/util.cljs```
@ibdknox Let us know if you have an objection to this. I can't find any references to this and git history indicates this was unused in the file from its first commit
