SDL2 goes into current

This evening, i accidentally check Slackware's changelog and i saw that SDL2 is now added into Slackware-Current along with other components (image, net, gfx, mixer, and ttf). ffmpeg is also rebuilt and now has ffplay since all the deps have been met (SDL2).

SDL2 is being used by many other projects. Running my dependency-checking script on SBo repository yields a lot of results:
