SDL2 released!

SDL, the “simple directmedia layer” we use as a base for our drawing and input, has reached a new milestone:

Don’t get too excited though, since this will mostly affect mobile users (where we use sdl2 by default). Now the interfaces are stable and there will be less compile-time problems when building gemrb. Depending on the status/buggyness of their platform specific bits, we may stop using development versions in our builds. That’s about it.
