RPC+GUI: adding destinations with list of service

RPC:
- Fixed javadoc for addDestination() methods. Method call choices
  based on passed parameters must be written as another header
  in order to look like separate methods in resulting javadoc.

GUI:
- Switch calls addDestination() to new implementation which can
  handle list of services in one call (prevent race condition).
- Use new calls in CreateFacility wizard and AddFacilityDestinationTab
- removed unused AddDestinationForAllServices from GUI
