Style tweaks

* Switch to Alegreya on the admin
* Customize Ace editor a bit (will do a custom theme eventually)
* Style the usernav a bit more
Organize styles better

Also some small optimizations
Fix grunt serve
grunt serve was failing because of a weird CoffeeScript compilation
issue in renderer.coffee (strangely, grunt dev worked just fine).
Adding explicit parens around limit and skip fixes the issue.
Since this was a minor fix, I also fixed some trailing whitespace.
I'll add linting to the grunt tasks ASAP.

Refactor TemplateEditor

So view gets re-used and not disposed. Better for memory and no visual flickering between templates. Side note, can't wait for HTMLBars...

- Embed role in users. Not sure if this is a good idea...

Fix tests

We need factory or fixture :)
