Made SimpleEntity GWT translatable (no more clone() method; no more DateFormat)
Removed Arquillian for now (will bring it back later when we can look into Shrinkwrap Resolver stuff)
Got ClientSyncManager testing under control by mocking the DataSyncService within the test
Fixed bug: new remote entities were sharing an instance between desired and expected state EntityManagers.
Fixed JaCoCo argLine thing (platform-dependent argLine profile was interfering)
Added test for deleting an entity
