[incquery-dev] IModelConnector rework

[András Ökrös <okrosa@xxxxxxxxx>]

Hello,

I would like to ask everyone who has free time to test the new
IModelConnector. That means testing the loading resourceset-resource
parts with multiple editors. As I changed them quite substantially;
I'm afraid to say, but it is highly unlikely that it is bug free at
the moment :).

Thanks,
András
