Add Instanced Adventure System

[TehFamine]

Create an adventure system that will ultimately tell the story of the game, but do so in a instance manner. Make it so the adventures can be broken down into a series of encounters that follow the story from chapter 1 to end. Then make it to where the actual adventure, the rooms, the exits, the items, armor, weapons, monsters, etc are all spawned on command and tagged with a unique identifier tied to that instance so it can be deleted when the character is done.

Maybe if time, add a way where other players can join that adventure in progress and have the content scale to their combined power level.
