Add support for Pets

[Volte6]

Description

Pets will be non-mob entities.

Pets will have passive or active (or both?) abilities. This ability may get better with pet level, not sure yet. Maybe pets will just grow in size/age.

Players can have no more than 1 pet, but may make it possible to swap pets in some kind of "pet hotel" type situation.

Pets can be given names, which will help identify them uniquely.

Passive Abilities

These are naturally applied gains, buffs, abilities to players, or special things that only happen at specific times.

• Stat gains (Strength, Speed, Smarts, Vitality, Mysticism, Perception)
• Player gets some enhancement or buff
• Pet may "magically" intervene in some event (prevent death for example)
• Carry objects for the player
• Skill specific bonus

Active Abilities

These are triggered during idle moments randomly. Possible more mature pets more often.

• Assist in combat
• Discover/Alert to something
• Steal an object from mobs/players

Losing Pets

Pets may die or otherwise get removed from player ownership.

Examining your pet will tell you how it's doing: happy, content, hungry, starving

Players should keep pet food on hand for whenever their pet is hungry. If your pet is able to eat, they will get stronger and bigger. Whenever a pet can't eat the player will be warned that their pet is hungry. Each time a pet is hungry and not fed, they will drop to a more dire state of hunger.
