fixed orientation bug in Bee_UIBoard

using (_allowedOrientation & interfaceOrientation) != 0 to check whether a specific orientation is allowed is definitely incorrect, since OrientationMask is only available in iOS 6, therefore, in order to reduce the total amount of code changes, I decide to write a custom orientation mask macro to force convert UIInterfaceOrientation into UIInterfaceOrientationMask. The solution wasn't good, could be discussed in further.
