fixed a issue with pinging Master-server
Sometimes initial TickCount is less than zero, so (Environment.TickCount - lastPing) can be less than "MasterPingInterval * 1000". That's why PingMasterServer() is not calling for a long time until somebody connected.
Tell the masterserver about it, so it can quickly remove games
from the list when they are finished, rather than waiting for the
5 minute TTL to expire.
- lobbyInfo.Slots is now a dictionary, keyed by the name of the PlayerReference that the slot is tied to.
- LockRace/Color/Team is now specified on the slot, avoiding map lookups in the lobby
- Observers are no longer tied to slots -> players will join as observers instead of crashing the game if there are no available slots
- Observers are able to change their name and color
- Game.CurrentMods property to query the current mods when no orderManager accessible
- Server sends mod versions to master server on ping
- Client sends mod versions on handshake response
- Validate match on server side of handshake, not client side
