- Fix Grid Entities coming back when exiting and re-entering a room. MODDERS READ FURTHER.

This fix is done by flooding every empty space in the room with decoration grid entities. I have no idea how safe this is, so if stuff starts breaking yell at me, quick!

- added a bajillionth argument to AddBossToPool, "rooms"! simply pass in a lua-ified room table, and it'll handle the rest. note that when using OnSpawn with rooms, BossAPI will pass in all entities spawned rather than the boss.

- Undo the fix for the thing that wasn't broken, except when it was.

- Added a new "Check" argument, a function can be passed in that returns the new weight for the boss. (This way you could, for instance, check that another boss is in the room, and if so add 100000 to weight, to have the boss always replace another)
- Also fixed an issue that occurs on some devices where entities in the boss room would not be deleted.

- Bugfixes (sound playing wouldn't correctly randomly play a sound if passed a table, HasBackgroundAttack would never return true)

Changed the warning slightly just in case
