ProjectDataSourceTracker (PDST) tracks changes to data sources.
To determine if a project contains a data source, the project's pages must be modeled.

At IDE startup, PDST starts listening for model set changes.

Even when just a component is added to a page, PDST checks each bean in the project to see if contains any rowsets.
This is the original design.

Instead, I think that PDST should only create a modelset listener when a project is opened and then remove the listener
once project has been modeled.  ProjectDataSource tracker already listens for project open and close events.

A new listener can be implemented to fire an event to handle the case when a database table is added to a page or bean.
PDST can listen for this event and update the project data source information.  Once done, the listener can be removed.
