__324 warnings in 42 files__ (coffeelint) have been fixed.

Mostly just unnecessary double quotes, unnecessary fat arrows, miss-spaced `->` and empty functions (`-> return`). I have not been able to run the specs on my setup, so please feel free to do so on your own (in case I broke something).

We deliberately use `@` everywhere except when it is by itself.  This would fall under the not by itself category since it is followed by a `::`.

Where we want to avoid using it is something like `new Buffer(@)`, we would write that instead as `new Buffer(this)`.
