TeamManager avatar add refactor

[ProxyismGH]

Description

TeamManager refactor
Added new addAvatar methods to the team manager to handle adding avatars.
Added new canAddAvatar methods to the team manager to check if an avatar can be added to a team.
Adding avatars through the new team manager methods to the players current team or the MP team will trigger entity updates.
Now by default, adding an avatar to the player will attempt to add it to the current team if there is space based on the appropriate configs.
This can be disabled with a new second param, some places use this(PlayerBorn, GiveAll).
If a newly accquired avatar is added to the team, a notice will display in the item/reward feed at the left.
Fixed adding avatars in multiplayer not using the MP team limit config
