Remove _sort_children from script bindings: _sort_children is an internal method which shouldn't be exposed to scripts. Added support for non-bound methods in MessageQueue: So we can use deferred calls without exposing internal methods to scripts. Added debug checks in CallableCustomMethodPointer: Adding method pointer callables to the message queue was causing crashes in case an object was destroyed and the same memory was allocated for another one. The new object had a valid object id but the call was erroneous. Release will be fixed later, along with Variant which has the same problem and is also fixed for debug only.
