Allow option to "Hot Exit" on close for macs.

[vadoff]

Currently, if you press the red x button on the window, it will close all files and not hot exit from the application.
The only way to get hot exit to work is to press ctrl-q or quit from the menu/dock each time, which can get a bit frustrating, especially if you forget to.

Please add a setting that can allow mac users to enable hot exit-like behavior on pressing the red x on the window.

When you press the x you aren't exiting the application, though...
