gmoccapy_0_9_9_6 - introduced plasma screen layout

ver. 0.9.9.6
- made a new config folder to show gmoccapy as plasma screen
- included some minor changes to be able to place user glade panels
  over the coolant and spindle frame, hiding the original widgets
  so plasma screen can easy be realized
  This will hide also the spindle speed label in gcode info frame.
- the tool info frame can also be hidden by a user glade file, because tool
  info is not needed for plasma.
- corrected an error in handling python calls in / for user glade screens,
  as example introduced plasma.glade plasma.hal and plasma.py demonstrating
  all possible communications
