[Qemu-devel] PATCH] ui/cocoa.m: verify with user before quitting QEMU

[Programmingkid]

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

wants to quit QEMU.
