Bug 605872 - Units dropdown list is not updated 

Add private API _gimp_unit_store_sync_units() which emits
"row-inserted" on each unit that didn't exist when the GimpUnitStore
was created, or when sync_units() was called the last time.

In GimpUnitComboBox, call sync_units() each time the combo is popped
up, or a unit is set on the combo.
