Create a system which allows game designers to create various keys for a game without changing the code.

This system consists of:

Key Ring Component

`UseKey`	Uses a given `KeyType` if it’s in the array of acquired keys

CALLBACK	DESCRIPTION
`OnKeyAdded`	Called when a new key was added
`OnKeyRemoved`	Called when a key was removed

A component which controls the lock state of an owner.

The component should have these parameters, functions, and callbacks.
