Code Culling - Mid Update

I have removed large amounts of NS2 code, and I am currently
reconstructing the game to work correctly.  Further code culling, and
re-working will be done to get this up to release standard.  Resource
usage of this version is much lower than the current release version.
Optimization and Culling Part1 complete

Removed AV outline, Made All buildings Digestable, lots of code cutting
and hacking.  Game is now running with a very minor bug, some models
require double click to place.
