Xxf86dga Mouse support: load lib dynamic if possible
* removed all USE_XF86DGA defines
* load Xxf86dga lib dynamic if possible and try to use it
** no hard dependencies or disabled support in the binary anymore
Project:
* added Debug in codeblocks projects
Added Linux Gamma Support:
* used wine gamme support (xvidmode.c)
** be careful - the whole desktop gamma setting is changed
** if the game crashes the gamma is NOT set to the original value
New Binary (use dga mouse again, gamma support)
Forgot to commit file changes in CMakeList.txt
