Summary: key translation

Initial Comment:
ScummVM doesn't translate keys correctly. When 
pressing e.g. a german umlaut key, I get whatever is on 
the english keyboard instead.

First I thought this would be a bug in SDL, so I wrote to 
SDL about it. I got a little demo source back from Sam 
Lantinga showing how to do things right. Here is the 
patch for ScummVM, could someone please check it 
in? Thank you!

In the initialization somewhere call:

/* Enable UNICODE translation for keyboard input */
SDL_EnableUNICODE(1);

Then in SDL.cpp in "OSystem_SDL::poll_event" please 
check whether "ev.key.keysym.unicode" is filled. If it is, 
please use that instead of "ev.key.keysym.sym". That 
was it. Here's a part of the sources I got from Sam:

if ( sym->unicode ) {
	/* Is it a control-character? */
	if ( sym->unicode < ' ' ) {
		printf(" (^%c)", sym-
>unicode+'@');
	} else {
#ifdef UNICODE
		printf(" (%c)", sym->unicode);
#else
		/* This is a Latin-1 program, so 
only show 8-bits */
		if ( !(sym->unicode & 0xFF00) )
			printf(" (%c)", sym-
>unicode);
#endif
	}
}

This code correctly gives me all german special 
characters.
