Ideas for adv
-------------

- Use roomExits and movement to check for possible exits. If looking north (1000) and going forward (1000) we
  check for 1000 in roomExits. Lets say that there is an exit there. Now, if looking south in the same room
  and going backwards we have looking 0010 and direction 0010 but still 1000 in roomExits.
  Solution is to shift roomExits two positions to the left for south. (and one for east, three for west).
  We need to make sure that bits go back around (ie 0001 -> 1000 for one place to the left).

- Room information should be stored in a file instead. That way we can call a roomLoad function with roomNumber
  and stuff will be sucked into a struct containing appropriate values.

- We also need a global variable of some kind to keep track of inventory and things the player have done/seen/
  manipulated.
