Recalled due to serious PT tracker bug
- improve PT tracker Z translation accuracy
- fix freetrack protocol breakage (issue #385)
- modules now go to to the
modules/subdirectory. they still work as usual. - slight accela gain changes to allow for lower sensitivity on non-inertial devices
- octopus doesn't have some axis inverted on the main display
- reduce translation range. no one used that high a range.
