Patch from Fox:

Browse source 
Add a FOV option in the menu. Range from 75 to 120 degrees (at 4:3 resolution), default is 90.

New userdef "fov". Equals the FOV in 360 degrees.

Update Polymost projection hack, so it compensates for the FOV or height of the game view.

Fix FOV in Polymer when the full status bar is visible. Now the FOV depends of the width of the game view instead of the height.
