Small 267 fixes

- Moverate and interp still need to be set on client connect until 268.
- Fixed some notifications getting overlapped by other chat messages.
- Minor improvements to the team shuffling system. When using the Hive ranking data, players are placed onto the team they can help the most when joining mid-game. Also, if there is a team imbalance, players on the larger team can switch to the smaller team even if teams are set to be blocked.
