gmoccapy_1_0_10 - spindle feedback changed to use only abs

ver. 1.0.10
- changed the behavior of the spindle feedback bar and the speed labels
  we do not change the bar limits from negative to positive, we use
  from now on only abs values! That is the reason I did include a additional
  abs in the postgui hal file
- corrected an error, not allowing to switch spindle on / off while program paused
