Need a more obvious way to change the Default Server

It is not obvious how to change the default server in Designer. I'd recommend a button/link on the 'Default Teiid Server' area to select a different server.

Also add the "Set Default Server" action to the Modeling Actions.... menu in the Advisor View.
