1.29 Update

Recently I became reunited (in a manner of speaking) with the most important person in my life, so progress has been less of a priority.  I have however continued to move along.

Recent changes:

• Optimized large parts of the pathfinding and targetfinding routines
• Cleaned up several bugs
• Decided to move to OpenGL graphics drivers for cross-platform compatibility (only in testing now)
• Increased accuracy of Trikes and Quads to increase effectiveness against infantry
