SDL2 port: version 8774

Hi folks,

I know it’s soon after the previous update, but there is a new update online.
The engine now uses SDL2 instead of SDL1.
Some of the improvements are:
-Better keyboard/text-input support. (Copy/paste to other application works for every OS now..)
-Better game-controller support.
-Steam overlay works and is supported.
-Less crashes.
-LGS has some additional error messages to prevent errors in scripts.
-The LGS run-time is faster and more secure.
-No more SDL.DLL dependency! :)

Good luck & have fun!
