/**
Provides a user-interface component for browsing through the set of
configured servers for editing and/or choosing connections.

To use, create an instance of pqServerBrowser, and connect its
serverSelected() signal to a slot.  If the user selects a server,
the slot will be called with information sufficient to start
the associated server.

You may want to use the pqServerStartupBrowser dialog, which
does all of the above, and starts the server for you.
