EDIT

adapting default permission goups according to #4111 (behaviour of TaxonEditor for users with limited grants [DISCUSS]) comment 8

added remote collection methods to service layer to be able to make remote calls on server side persisted collections

fix CacheUpdater

minor

• renamed getBaseUnit() to baseUnit()

• added util method to get for getting a CDM entity (used in authenication/permission framework)
  • made use of this method where the type of the parameter was too general (like object)
  • made getBaseUnit() of DerivedUnitFacade public

• refactored to use "base" unit wherever possible (base unit is derivedUnit or fieldUnit)

handle setType in DerivedUnitFacade better

some minor changing for handling getType()

implementing #4082 (implement default permission groups)
