History
Werner Almesberger 9f9e77d025 atben: include the position of fiducials in atben-pos.csv 
The fab was looking there for the positions (alas, in vain). Seems as
good a place as any.

- atben.brd: bumped file version to 20110607 (didn't change the version
  printed on the layout since the layout itself didn't change)
- atben.brd: changed fiducials from "virtual" to "insert+place", to
  include them in the position report
- atben.brd: renamed the fiducials to give them unique names
- Makefile: bumped fab files version to 20110607

PCB manufacturing:

- do not print PCB edges on front/back copper
- do not print component values on silk screen
- note that the transceiver is "upside down"
- the center (!) of the board edge line marks the true board edge, e.g.,

                             Edge line (5 mil)
