List of entities without assigned objects can be displayed as error details in error dialog.
See #42
When new object is no longer assigned to any entity, it is removed from the list of new objects.
Fix #43
Fixed some NPE (probably mostly silent)
Webservice urls are no longer hardcoded but loaded from property file
Hack fixing mouse events etc is less hacky now
Entities without assigned objects now have orange background
See #42
