allow setting of a 'default connection' for linqpad to use on startup
When I start up linqpad, it's always to use the same database (the database of the product I work on), but by default it lists "no connection". Rather than constantly making me set the connection, it would be nice to be able to flag one as the default connection (similar to a default printer).
Another option would be to default the connection to whatever was last used (this would be as effective for me since I'm always using the same one).
Yet another option would be that if there's only one connection defined in the Connections window, default to that one.
