[SDL] Alt-F4 not working on Windows

[Erik]

Unless I missed something in a prior mail, all we are talking about here is
whether or not SDL will honor Windows sending an alt-f4 as a WM_QUIT event
(that you still have to handle yourself in your code) or instead send it as
an alt-f4 keypress event to give the programmer maximum flexibility. Not
exit without program intervention or anything like that.
