quakespasm/Quake/keys.c
Eric Wasylishen 1b6abd0e04 in_sdl.c, key.c: Fixes agreed on with Sander: 
1. Remove Key_IgnoreTextInput(), and simple always send a Char_Event when
we receive TEXTINPUT (SDL2) or the unicode field of a KEYDOWN event is
filled (SDL1.).
2. Remove handling of K_KP_* in the menu/console, since they cannot be
relied on to not also send text (see issue described above). The handling
of K_KP_ENTER can stay, since we do know that it never sends text.
3. Remove the interpretation hack for the numpad, since it will no longer
be needed (and doesn't currently work for SDL2 anyway); if a numpad key
generates text we will handle it (because of "1"), if not then it will
simply be if ignored (because of "2”).
