Matt Guthaus 7f5e6dd6f8 Fix unconnected supply pin bug in supply router. 
Simplified some of the supply router pin groups so that it assumes
each group is fully connected. When computing enclosures of the
pins on the routing grid, it will remove disconnected enclosure
shapes to keep things connected.
