Ctrl+Q closes application and stops rendering

[phw]

Normally when just closing the Peek window while Peek is rendering, it will continue in the background.

Pressing Ctrl+q however closes the application directly, circumventing the current implementation on the window close event.

@phw What if we overwite crtl q to behave as the window close event?

[phw]

It's not just Ctrl-Q, it's also "Quit" in App menu or everything else that closes the application directly(as opposed to closing the window). That means the application close event needs to be interrupted and everything handled there. Might need some refactoring, but haven't looked into it yet.

This was easier than I had originally thought :)

Yeah pretty cool, very nice!
