Fluid PR 313: update subtype menu to show "Normal" when deactivated.

Based on jdpalmer's pull request:
If the subtype menu is disabled because there are no subtypes, the deactivated menu will still display the subtype of the last widget that had a subtype value. Clearing the menu when there are no subtypes fixes this minor inconsistency.
