Improvements to enable Edit/Show of GxsGroups.

NB: The actual update doesn't happen yet - mainly just the display of info.
  - Fixed up Constructor, and loading of MetaData via TokenService.
  - Fixed up Enabled / ReadOnly for Show.
  - Updated children to match new functionality.
  - Fixed up Show in Circles Dialog too.
  - removed a few compile errors.
