3.1 branch editing label question type loses access to edit parent.

[danmarsden]

when editing an existing label that has previously had a parent question set - the interface gives no ability to change/view the selected parent. The parent still shows on the main questions overview page.

(using postgres if that makes any difference.)

Hmmm... It looks like the "label" question has been specifically excluded from having a dependency. I'm checking to see if this was intentional, although since it was allowed in 3.0 and prior, it seems like a mistake.
