Fixes for spawn points, models, etc

Version 0.91 fixes some problems:

• Models inside rocks. Since these were mostly grasses it didn't make sense for them to be on top of the rocks either.
• Flags sometimes being inside of rocks
• Spawn points and headquarters locations sometimes hanging around in mid air. Spawn points were automatically dropped down by COD2, but the headquarters had an unpleasant tendency to hover in midair in devilishly difficult (or impossible) to capture locations.

There are some big changes to the COD2gen map generating program - you can now customize many things that were previously hard-coded, including

• textures
• models
• relative liklihood of different region types, or to have no regions made at all (terrain only)
  
• number of regions per map
• map size
• building and ladder dimensions
  

Probably not that many people will be too keen on editing the XML configuration file by hand, but there is a GUI in the works.
