[SDL] Alt-F4 not working on Windows

[Jacob Welsh]

That's the point. Alt-F4 is part of the operating system's interface; 
that should not concern the programmer any more than "minimize" or 
Alt-Tab. If you check for Alt-F4 events yourself, you're making the 
unreasonable assumption that all operating systems supported by SDL have 
this convention, which is not the case. On Linux it is perfectly 
reasonable for the user to remap Alt-F4 to something else, and have some 
other shortcut for "close".

On Linux, the Close button, Alt-F4, Ctrl+C, SIGTERM etc. all generate an 
SDL_QUIT event; I assume this is also the intended behavior on Windows, 
and it ought to be if it's not.

(A few games I've seen override this behavior, which I consider very poor design.)  Since by default, <ALT>-<F4> means "quit", it should always generate a SDL_QUIT event, not a SDL_KEYDOWN event.  (Same goes for <Command>-Q on Macs.)
