Send message if a mob gets killed by something else than a player (e.g. by another mob or plugin).

Note: The killed event type is now called killed_player. The old one now exists as a short hand in the messages configuration to define a message for both event types (player and other). From now on, use killed_player in the /talkingmobs toggle command and for the global events configuration in the config.yml.

• 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

Allow to configure which events should show a message (attacked, interacted, killed, spawned). The "spawned" event requires a list of spawn reasons for which a message should be shown.
