Title: Quick and easy performance gains

Based on some research @vladzinculescu and I are independently doing, here are some slight tweaks to the IDE that won't make it blazing zomg fast, but it's a start.

1. Simple and lame JSON minifier that'll be used by infra for its JSTs
2. I spritified all the famfamfam icons for files, as well as the ones for folders; I changed code in appropriate places to support these (filetree, openfiles, save as, new resource)
3. The zen background gets loaded whenever a new file is loaded. Essentially this means if you have files open, leave the IDE, and come back, the zen bg is downloaded. It's not a trivial thing as the background is pretty heavy. This now downloads the bg when the button is actually clicked
4. I deleted some famfamfam icons that were not being used at all
