- Changed Buoyancy controller to be area based.  It currently still only uses objects you tell it to but that's easy to change.  Need to change the BuoyancyControllerToy art to show a region.
- Modified the debug-draw to not use the b2Color.  Still need to expose the selected debug-drawing colors to the scripts and try to use stock-colors for the defaults to make it easier.
- Modified how TypeVector2 works.
- Added more string-based utility to Vector2.
