sys_sdl_win.c: Call SetProcessDPIAware if available (Vista and above) to opt out of the OS scaling our window on a high-dpi display.

SDL (both 1.x and 2.x) is buggy and can't deal with scaled windows.
But we'd probably want to call this anyway beause it give us full-resolution windows.

Minor cleanups.

in_keys.c: Key_ConsoleBindable: remove redundant check, this is now handled by Key_KeynumToString/Key_StringToKeynum.
in_sdl.c: IN_SendKeyEvents: use a single method for checking whether we have a keydown or keyup event.

Xcode project: created "QuakeSpasmSDL2" target. It expects a copy of SDL2.framework to be in /Library/Frameworks

changes from "QuakeSpasm" target:
- remove double quotes around LIBRARY_SEARCH_PATHS values, this breaks linking on my OS X 10.6/Xcode 3.2.6 system
- drop ppc support
- add USE_SDL2 define
- bump minimum sdk deployment target to 10.5 as required by SDL2

Tested on OS X 10.6.8/Xcode 3.2.6, and OSX 10.9.4/Xcode 5.1.1.
