Fixed bug 2277 - Hardware keyboard control key sequences don't get reported

Browse Source 
chw

Control key sequences from hardware keyboards (wireless/USB/bluetooth) get not properly reported on Android devices.
The attached patch uses the idea from http://stackoverflow.com/questions/12337117/capture-all-ctrl-under-android to make control key sequences appear as normal SDL_KEYDOWN events instead of cooked text input.
