vialtray: ready for first test run (on-going)

- doit (GEN): corrected name of toolpath generator
- doit (rdata): fixed typo ("rdate" vs. "rdata")
- doit (Z): set Z depth here, to avoid manual depth adjustment
- doit: don't use cameo - we compensate for the tool size in tray.pl
- doit: increased feed rate from 2 mm/s to 4 mm/s
- doit: clearance is above top layer, so 5 mm are more than enough
- tray.pl (zf): increase floor depth from very conservative 15 mm to
  17 mm
- tray.pl (zs): increase depth step from 2 mm to 2.5 mm to accelerate
  milling
- tray.pl (mw): increase wall thickness from 2 mm to 2.5 mm in order to
  enlarge gap between sides (was smaller than tool diameter)
- tray.pl (r1): stop 2 steps before the edge, since we have the outline
  as another radius-like step
- tray.pl (do_col): account for tool radius
- tray.pl (do_circles): lift the tool after each disc, not only after
  each column
- tray.pl (do_cols, do_circles): temporarily skip 1st column
- tray.pl (main): do circles before the outline, to reduce chatter when
  cutting the outline
- tray.pl (main): since we're no longer using "cameo" here, don't print
  directives for it
