(WIP) Menu/Popup Height Fix

Right now it is just the status menu. But I noticed that some dialogs are based on the size of the terrain. This doesn't quite work in the SDL version, since tiles can be of various sizes, so I figured we need to change them so things appear correctly.

I used FULL_SCREEN_HEIGHT rather then TERMY for this purpose. I also noticed the map editor has an issue here as well, which will need looking into. However I cannot at the moment build the SDL version. So I need to do that before I can go about fixing all of the height problems.
