SDL2 support (mostly)

Browse source 
Makefile is adjusted, it compiles and works mostly, but
* For some reason (bug in SDL_GetRelativeMouseState() ?)
  mouse input doesn't work properly.. it seems to be bound
  to window borders, even if input is grabbed
* some keys can't be used anymore because there's no SDLK_*
  for them anymore (gotta find out if this is important)
* Maybe some of the changes need cleanup
