Uses SDL_Keycode to implement basic keyboard layout support, specifically for text fields.
Console variables:
kb_ignorelayout (default Off), CV_SAVE: Turn on to disable keyboard layout support.
C:
event_t has one new field:
INT32realkey (after key): The key, generated from SDL_Keycode instead of SDL_Scancode -- what key uses.
When the event_t is not generated from a SDL_KeyboardEvent, equals key.
Lua:
keyevent_t userdata sent by the KeyDown and KeyUp hooks has 2 new fields.
The original fields name and num remain, and retain their behavior of assuming you're using the QWERTY layout.
stringrealname: The name of the key according to the current keyboard layout.
intrealnum: The numeric code of the key according to the current keyboard layout.
