Add short-range vertex-based pathfinder. Integrate new pathfinder into unit motion code. Change obstruction system to get rid of circles, and differentiate structures from units. Make PositionChanged messages synchronous. Try to prevent some accidental float->int conversions. This was SVN commit r7484.
