Fix lobby room and userlist updates

[Moutix]

If I didn't send the lobby user list, it's because it's limited to 255 users do we really need to send it?

I dont think sending the lobby userlist properly is a bad idea. That said i can see it not being a priority.
What i do think is a priority is the room list(without it users cant properly recognize/join rooms. Even the state is important in my opinion(a player in a hurry might be looking for a room not in a game).
And, if i remember correctly, the lobby userlist and room list are sent in the same packet(therefore not updating the userlist but updating the room list wouldnt make much difference i think)
