Draft of TokenEngine with In-Streams instead of ModuleDataSource (not working!)
Changed Version to 6.6.1
Extended DynamicEntityPropertyAccess.GetProperty() with support for List of Entities (e.g. "Category:First.EntityTitle")
Adapted TokenEngine to use In-Streams instead of ModuleDataSource (works except Presentation-Entities)
Extended UpgradeModule() with 06.06.01
Added 06.06.01.SqlDataProvider which renames AssignmentObjectType 4 to "Data Pipeline"
Undone all changes in TokenEngine so this branch can be merged to master safely
Fixed some whitespaces/Tabs
