[Engine] Grimm "spawning"

To get Grimm, player goes to the tavern as directed by the merchant. Player has to talk to the tavern owner where he tells the player where grimm is (out back, player can't go through until they talk to the tavern owner)

Grimm will be lying on a table in the corner, when player walks up to it the Grimm static mesh will be on the table, will disappear

Grimm will "spawn" and follow the player around for the rest of the game.
