Remove Gnome PPA
Remove Java and Last.fm for the time being (no solid packages)

I'll probably package these myself. Maybe it's worth seeing if RPM Fusion would
accept the *-installer packages, as some of this stuff is on their wishlist.
Update gitignore paths
Add carrier repo for ST3 installer
No longer supports Ubuntu, no longer requires apt
LAMP development recipe works on Fedora now
Work around silly git package problem (__git_ps1 never defined)
Work around Gnome Terminal dconf bug

Newer versions of Chef don't set up the environment correctly. Work
around the stupid oversight by just using sudo.
PPAs be gone! Also, ensure NPM is installed (separate package)
ST3 PPA removed
xchat's configuration is in a different location
Perform a somewhat less heavy-handed kill on ST/xchat

This ensures they cleanly write their configuration.
VirtualBox has to be installed from Oracle's own VM repos
ITK is *still* broken in Fedora (now 4 successive releases at LEAST)
Tons of stuff has been removed
