enh: add hotkey for "toggle fullscreen"

Binary package hint: xvnc4viewer

It would be nice to have a hotkey in xvnc4viewer to toggle fullscreen mode.

I have needed VNC a lot lately for work, and often need to toggle between fullscreen mode and the regular windowed mode. I often only need fullscreen mode for a few seconds, so I could end up spending half that time just moving the mouse to the correct "F8 menu" item while turning it on and off.

For my own use, I've hardcoded a hotkey into the program to speed up this process, instead of having to hit F8 and mouse around to the option on the menu. This is by no means a good patch for general use (since it's not documented or configurable), but it shows at least the minimum necessary to make Hyper-f activate the fullscreen toggle.

This patch applies cleanly and works on xvnc4viewer 4.1.1+xorg1.0.2-0ubuntu7 (hardy).
