MatchMaker Filters

Aside from custom attributes, ListMatchRequest seems to lack some basic filtering options:

It always returns matches that are...
1. already full.
2. empty - which you then can't join, resulting in timeouts etc.

Speaking of full matches: The size variable in CreateMatchRequest seems to be ignored. I've set it to 2, yet still 4 clients could connect. Setting it to 1 results in an error.

It would also be handy if the Response would contain information about whether the match is in the lobby or game scene when using the NetworkLobbyManager. Then you could filter for matches that are already playing, or still idle in the lobby, waiting for players.

Feel free to correct me if I overlooked something.
