Fixed bug 3461 - Implement TEXTINPUT events for Haiku

Browse Source 
Kai Sterker

Apparently, SDL2 on Haiku does not generate SDL_TEXTINPUT events.
Attached is a patch that adds this functionality.

Tested with SDLs own checkkeys program and different keymaps as well as my own SDL application and German keyboard layout to verify it generates the expected input.
