gmoccapy_1_2_2 - support now also matchbox-keyboard

tooledit-widget.py commented out one print statement

ver. 1.2.2
- changed the way the window size and position is
  handled, as before the default values did appear
  several times in the code
- If no virtual keyboard could be initialized, we
  disable now the corresponding part on the settings
  page and the related button. Check will be done
  for <onboard> and <matchbox-keyboard>
- starting gmoccapy did throw an error to the terminal
  that a widget could not get default. Finally I found
  the reason, the glade file did contain a property
  "has_default" and that is not allowed by builder.
