*: HUUUGE changes
animia has been renamed to animone, so instead of thinking of a
health condition, you think of a beautiful flower :)
I've also edited some of the code for animone, but I have no idea
if it even works or not because I don't have a mac or windows
machine lying around. whoops!
... anyway, all of the changes divergent from Anisthesia are now
licensed under BSD. it's possible that I could even rewrite most
of the code to where I don't even have to keep the MIT license,
but that's thinking too far into the future
I've been slacking off on implementing the anime seasons page,
mostly out of laziness. I think I'd have to create another db file
specifically for the seasons
anyway, this code is being pushed *primarily* because the hard drive
it's on is failing! yay :)
