New atusd errata and a few small CAM updates.

Browse Source 
- atusd/ERRATA: added errata section for version 20100908
- atusd/cam/doit: increase tool clearance from 1.5 mm to 2 mm
- atusd/cam/pcb.pl (cut): cutting counter-clockwise did not reduce burr.
  Removed reversal of cutting direction.
- atusd/cam/pcb.pl: made area selection formulas easier to understand
