IndyPets - Independent Pets

This update brings major improvements like:

• client → server config synchronization
• /indypets whistle and unwhistle commands
• rudimentary particle effects as an alternative to text messages

Config synchronization means that each player on a server can now have their own settings!
The settings are automatically synchronized simply by having IndyPets installed.
Vanilla clients can still join an IndyPets server, but they won't be able to have personal settings (... yet?)

The whistle and unwhistle commands are for making all nearby pets follow you or be dismissed again, useful to command your army of wolves!
Both commands can take an optional type of pets you want to address.
Auto-completion will show you which types of pets are around, so no need for guessing.

When text messages are disabled, making a pet follow you will show "happy villager" particles, aka green sparks.
(The reason for not using heart particles here is to make it less confusing when Pettable is installed)
Dismissing a pet will show "angry villager" particles, don't worry, they still love you!
