Werner Almesberger 38bea8ec54 README-SMT: various small clarifications 
- atben/README-SMT, atusb/README-SMT: added "component to "orientation"
- atben/README-SMT, atusb/README-SMT: added "drawings" to "footprint
  reference"
- atben/README-SMT, atusb/README-SMT: mention once more that the automatic
  insertion file is for the front only

README 

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)
