Resourcepack support is broken

[kennyvv]

Currently loading extra resourcepacks is a bit broken...
They don't load at all at the moment, except when restarting the client. They however, don't work properly when doing this either.

When you have a resource pack selected and reload the game. Go to options and it will error because its trying to read the resource pack that is already in use

Update: they now load & reload.
Memory usage is pretty bad however, especially when reloading them. Seems we are leaking somewhere.
Animated textures aren't behaving properly either, seems to be an issue with resourcepacks requiring optifine maybe. Need to investigate.
