We should be able to sort lobby games

[NBKelly]

Games are currently sorted on the classifiers open -> time created.

We should be able to sort games - perhaps a little classifier at the top.

I'm thinking:

• default (what we do now)
• alphabetical (dictionary ordering)
• numeric (regex match for numeric content, sort based on that)

The last one is explicitly intended to help tournament organizers quickly locate the top tables - ie for streaming.
