Added "tamed" event showing a message once a mob is tamed
Added "version" sub command
Prevent spamming of messages (e.g. while attacking mobs or interacting with them)
Send messages if a mob is looking at the player (and the player is looking at the mob)
BREAKING CHANGE: Moved messages and per player configuration to separate files - Mob messages are now configured in messages.yml, per player configuration is saved in players.yml
