1) Added bookmark folder editing... this basically makes this extension a graphical bookmark manager lol. It wasn't my intent or anything, but the folder edit & delete buttons were actually still there and were only kind of visible on mouseover.  So I just decided to hook things up and basically complete our Bookmark API usage. I fixed some dialogs and make things more contextual for what the action being done was.

2) Completed usage/migration to using icon fonts, so no images in /images are needed anymore :) Now both the folder and + sign icons are being scaled and used nicely unlike before, this helps RAM usage quite a bit as well, so now all the graphics are actually from the .woff font file, and the newtab page load speed is 40ms faster than before :D
