gmoccapy_1_0_2 - solved active gcode bug

ver. 1.0.2
- solved a bug in getting active gcodes, because I took also the first
  element of linuxcnc.stat.gcodes, but that seems not to be a gcode, but
  some kind of control number or something like that, so it causes wrong
  code and changed gmoccapy behavior in an erroneous way
- In this bug finding I also needed to change the gladevcp widget combiDRO
  to get the correct results
