Changes
* Relation Editor uses the correct Icons when displaying MetaProperties now (consistent to Details View).
* DisplayList uses the correct Icons when displaying MetaProperties now.
** Having more than 500 Metaproperties in the database caused an irritating issue when trying to set the MetaProxy Property Target. This issue is solved now.
* Staging (local compile) the customizing provides a symbol and the sourfile now. This is a prerequisite for debugging the customizing.
