Chat page revamp, per-group game lists, and game list filtering

[anoek]

@BHydden

On that note, how hard would it be to list beside each game how many people are spectating it / connected to game chat?
That’d be a really useful feature!

Thanks for the reminder, I was meaning to add that in

@BHydden

Also, the ability to list special review / demo boards in the case of relays of live international tournaments would be a sublime addition

That capability I’m saving for a broadcast / tv kinda page
