Add optional multitouch support to X11.

Browse Source 
Thanks @TheBrokenRail for a patch proposal based on example code from esjeon (patch #322).
See https://sourceforge.net/p/irrlicht/patches/322
Original example code here: https://github.com/esjeon/xinput2-touch
Users have to enable _IRR_LINUX_X11_XINPUT2_ in IrrCompileConfig and link with Xi to make this work.
I rewrote the patch a bit and have no system for testing here, so this still needs some testing.
I also backported EET_TOUCH_INPUT_EVENT for this from the ogl-es branch.
