Set the login Screen Resolution

Currently you can default a resolution for any user.

This however does not effect the login screen for gnome, kde or other GDM's;

X picks the first resolution in the screen config in /etc/X11/xorg.conf

So if you have a the line

    Modes "2048x1536" "1920x1440" "1280x1024"

etc, on a 22 inch CRT, you get a very nasty login screen

However X picks the first in the list - so if we had a applett that allowed you to change the order (pick one to be the first), then the login screen resolution could be configurable;

This would also effect the default resolution for all users.

so a good order would be

    Modes "1280x1024" "2048x1536" "1920x1440"
