Pretty icons and tooltips

[KTKate]

Let me know any thoughts or suggestions since I kind of just went off on my own here.

I also deleted application.hbs. It didn't see to be being used(in favor of the pods style application/template.hbs) but maybe there was something I didn't understand?

Can you attach before/after screenshots?

[KTKate]

Yeah I'll fix the tests and make some ss.

Side Note: I can't figure out how to run the tests locally. I get 37 fails locally.

All my changes are in peach-ish bar. The close, add a pane, show/hide file tree, and collapse/expand icons. The tool tips for these as well. I changed the expand/collapse icons because they suggest a maximizing/minimizing of the file tree pane rather than expanding/collapsing the folders within. The old tooltips also took quite a while to appear and could potentially be overlooked.

Please import the unminified version. Ember CLI will minify in production.

I will need to compile this. I'll see if I still have the files or make a new one.
