ui/cocoa.m: verify with user before quitting QEMU
This patch prevents the user from accidentally quitting QEMU by pushing
Command-Q or by pushing the close button on the main window. When
the user does one of these two things, a dialog box appears verifying
with the user if he or she wants to quit QEMU.
