Some very weak checking to ensure that multiple compile/dependency check operations aren't started at the same time (in the event that the user hits save twice in quick succession, there was a situation where performDependencyCheckOnFile: would delete the dependcy values, then a second instance of handleLessFile: would start before the old performDepencyCheckOnFile would finish, ending up in a weird state).
Fixed issue of performDependencyCheckOnFile: breaking everything sometimes (turns out a lot of the code I'd written when I first started this was chock full of Bad Things, big surprise!).
Began using the site UUID to maintain connection between a Site and its LESS files (mostly for display purposes).
Fixed some issues with showing/hiding windows, and with registering files.
Added zip of version 0.4
