Added the new Tribal minigame:
- In this event, two teams are going to try to destroy the enemy's totem. Players will be allowed to build (without being able to destroy the original arena, only placed blocks), so try adding some building blocks to make the battle more strategic.

- The first team to destroy the enemy's totem is going to be the winner.

Also:
Fixed an issue where players would stay with flight enabled after cancelling speedbuilders.
