Allow publish keypad hotkeys

@Piyush: When on the designer, allow keypad hot keys to be set for the Publish, Live Form and Test Form actions? I am referring to the options on the top right? For example, on Windows, Ctrl + Shift + P would Publish the form. The right key combinations need to be researched. It would be further desirable to have the hot keys configurable by the user. This is especially helpful if the chosen defaults are already in use by another program.
