Title: SDL: Added antialising support.

Just a quick few lines to add antialiasing support to OpenGL under SDL to improve graphics. If enabled, objects blend into the background properly rather than having jagged edges. I remember in the good old days I always forced it on the graphics card only for this game.

It can be enabled in the config file by adding "antialiasing=16". Valid values are 2/4/8/16 or anything your graphics card (and SDL) supports.
