Starting thumbnail code with a management command to generate thumbnails.
Added PIL to requirements.
Moved a bunch of constants to the constants file. More thumbnail stuff.
Shits all broken. Only works for gifs for some reason. PIL A SHIT.
Looks like generating thumbnails from older images works. Woooo!
I think this should all work. Probably.
