Allow wolves to attack teammates

In vanilla minecraft, mobs will not attack other mobs that are part of the same team. Teams have a 'friendlyFire' attribute, but this only allows players to attack each other, and does not affect mobs aggro.

This is particularly problematic in life series mods, that usually assign players to teams based on their life counts (green, yellow, red, etc.). This means that dogs owned by a red life player will not be able to attack other red life players.

This mod removes the team checking that mobs do when attacking a target. It will allow dogs (wolves) to attack other players and mobs in the same team.

NOTE THAT THIS MOD IS EXPERIMENTAL AND WILL AFFECT THE BEHAVIOR OF OTHER MOBS AS WELL. IF YOU USE TEAMS IN ANY MORE ADVANCED WAY THAN JUST COLORED NAMETAGS, PLEASE CHECK THAT THIS MOD DOES NOT BREAK STUFF. The fix affects any mob to aggro any other mob of the same team. I have literally done 5 minutes of testing, so the chance that this breaks something is very high
