Kari Salminen f5b2e69522 Fix Operation Stealth's 2nd arcade sequence's revolving doors. 
- Now the doors actually do revolve when before they didn't.
- The fix was to alias the 9th background with the collision
  page directly when loading collision page data. This way
  changes written to the 9th background go to the collision
  page and vice versa (And there were changes in the labyrinth).
- Also converted _bgTable from a pure array to a Common::Array
