Title: Patch addressing Hotkeys feature.

This patch addresses issue #309 and makes the following additions:
1. Esc key exits full-screen mode, if it is not in full-screen mode, closes iv.
2. F11 toggles full-screen mode. (F2 was suggested in the issue. I felt F11 was a more 'popular' alternative.)
3. F4 toggles fit to window.
