Misc bug-fixes and cleanups all over.
$.ajax() call to load the icon-fonts, it's the best way to load such fonts and it halves render speed for me, jQuery render time used to be ~100-110ms, now with the AJAX call to adaptively append the CSS rel link makes my page render time go to ~40ms, as fast as Zepto renders since other libraries try to be asynchronous loading resources by default but I'm just doing in manually now. This AJAX call causes a massive leap in render performance vs most other optimizations.
Options page background adaptively scales width.
generateFolderList() function put into the common initialize function.
