Added support for Completing on the Cylinder Type delegate

Browse source 
I had to immprove the TankInfoModel with two new methods,
insertRows and setData, because the delegate used this
model to show what kind of Tanks we are offering.
Since the user can enter a new type of Tank, it's important
to add this tank to all lists using the delegates.

I Also added two new methods on the delegate itself,
to correctly shows the data, and set the data on the
model. This also will help dirk with a working example
on how to edit things while using a delegate.
