Session type could be also selectable via url params

url params can't set the session type though, so I don't see a point to doing it that way.

I mean aside from the point that for this grid it's language agnostic and doesn't care if it's python OR groovy. Would rather there was some way to connect and get a table without specifying a language if you're not going to be running commands.
