Fixed bug 1616 - SDL does not use values set with SDL_GL_SetAttribute on Android

SDL does not use values set with SDL_GL_SetAttribute on Android.

I attached a patch which adds this functionality and makes it possible to set
(for example) depth buffer size or anti-aliasing in the actual application
instead of modifying the Java source (which seems currently the only way).
