Read Open States from Excels (#1557)

* Make sure we never access PlayerOpenStateManager::map directly.

* Read OpenStates from excels.

* Add defaultState

* Replace hardcoded open states with the ones read from excels.

* Don't send change notify when unlocking on login.

* Add open state blacklist for default unlocks.

* Add a way to temporarily set open states for dev

* Remove old OpenState.java

* Fix UnlockAllCommand

* Change condType to an enum.
