Version 3.7.1 for Spigot 1.9
Allow collisions between default players to be configurable using
allow.collisions (boolean). Collision behaviour is controlled using the
Team/Scoreboard API, since LivingEntity.setCollidable(boolean) is hopelessly
broken in the current Spigot 1.9 build.
Note, also that ModMode now uses the main Scoreboard rather than creating a private one.
