Fix all jshint warnings

[usernamenumber]

This includes all of the warnings listed below, and the app seems to work, but a quick sanity check would be nice.

ember test fails, but then it does that with a clean checkout of master for me.

We can use travis to test this ;)

[usernamenumber]

Well, Travis fails, but that's expected right? Since I assume it's not just running jshint but the ember tests as well. Any objection to going ahead and merging what we have for now?
