Fixed bug 3429 - Update AM_PATH_SDL2() to also check for SDL2.framework

neoaggelos

It is common for Mac OS X to use the SDL2.framework instead of the classic UNIX dynamic lib.

Therefore, it makes sense for AM_PATH_SDL2() to be able to locate it. Attached is a patched sdl2.m4 (updated for that purpose).

Changes:
* look for SDL2.framework ONLY if pkg-config and sdl2-config tests failed (this is to ensure compatibility with the old behaviour)

* adds option ('--disable-sdlframework') to retreat to the old behaviour

* adds variable 'SDL2_FRAMEWORK' for the user to specify the exact path to SDL2.framework (e.g. if it is installed in a non-standard location)

Open to suggestions for further improvements
