Import to shelf / mq fails with non-clean working directory
When you try to import into a shelf or mq patches and your working directory has uncommitted changes, a "Working directory is not clean! View changes..." message is shown and the "Import" button doesn't do anything.
Ideally the Import button would be disabled when attempting to import into the Working Directory or the Repository, but nothing should prevent you from importing into the mq or shelves.
An additional enhancement that would be nice would be to have a "force" checkbox that allowed you to import despite there being uncommitted changes.
