Post Demo Bugfixes

yhp19
- Fixing the Rightangle (2-4 Segment) case for the Autorouting algorithms. Equidistance is attempted whenever is possible (more explanation in the code analysis)
ad3919
- with help of yhp19 in understanding routing code
- Dragging does not work correctly in some instances
  - Opposite Side, (standard Issie) works as expected
  - Same Side, forces wire between two ports (as if it was opposite side) instead of only away from ports
  - Right Angle, prevents movement as both ports are preventing movement perpendicular to their direction
- Position of auto-routed wires has been fixed for some orientations
  - multiple 4 segment right-angle cases
