gmoccapy_1_3_4 - virtual keyboard "bug" not initialized settings correct

ver. 1.3.4
- if no virtual keyboard was installed (nor onboard or matchbox),
  the checkboxes on the settings page has not been sensitized and the
  settings has not been reseted correctly from the preference file
  Thanks to Roland (concierge) for finding this one
