Quickbattle scrolling bridge menu mod

This will create a scrolling menu for the bridges, otherwise some bridges get knocked off the screen. I don't know if this is compatable with QB2.02, and I don't have any instructions for it or the name of the author, so make sure you back up your current quickbattle.py before you install this. Also, make sure whatever other things you install afterward do not overwirte this file with another version.
