gmoccapy_1_0_2 - solved spindle bug

ver. 1.0.2
- solved a spindle button issue and included a check so it
  is no possible to exceed the limits of the spindle with
  override values. i.e. a spindle has a max of 6000 rpm and
  the user enters S 5500 M3 now he can increase the spindle
  override, but it will be limited by 109 %, because otherwise
  he would ask the spindle to run faster than allowed.

ver. 1.0.3

  mode, because there is the "EXIT" button
