Container field and the Range Wizard

[akeym]

If the Container field is to be visible on a form, its selection should be used to limit range selections, and possibly other values. This should apply in all cases, not just global..

difficulty: selecting a container on an already existing object should not clear or alter existing IP/range selection. Warn user if they select a container that doesn't have the selected range assigned to it, and allow them to cancel the container change.

Currently the list of ranges is determined by the users current ctnr. The only case we need to worry about is global.

I propose we move the ctnr field above the range wizard form to simplify this on the user end.
