Fix for issue 1168. Whenever the database is changed load all of the currently used relation names in a backgroud thread. In the event that the user opens the add new relation sheet during this process, the ability to enter a relation name and confirm the addition is disabled until the retrieval process is complete. There is also a new progress indicator on the add sheet to indicate this.
