Mouse holes and micro_interact-able things, you need to be inside them to use their interaction prompt, so you aren't allowed to instantly teleport back to a tunnel for leaving the prompt open or whatever!
Adds a var and a proc to all objects in the game!
If an object starts with the 'micro_target' var enabled, then it will obtain the 'micro interact' proc as a verb on initialize.
The 'micro interact' proc, allows micros and other small mobs such as mice, to hide inside of whatever the object is. Additionally, those inside one object can use the verb to move to an adjacent object that has the 'micro_target' var.
Non micros/small mobs can also use the 'micro interact' verb to attempt to extract anyone who might be within the given object.
