Clean up of the input selected for the opengl x window in linux. Fix a potential segfault when taking a screenshot (happens consistently when using "Save Targets" from the video debugger window). Fix a memory corruption error that results from the wrong image size being passed when dumping textures. Make the screenshot hotkey configurable. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6067 8ced0084-cf51-0410-be5f-012b33b47a6e
