MouseChildren inconsistent

[MSGhero]

The mouseChildren property within FlxMouseEventManager says that it disallows overlapping objects from receiving mouse events. However, this is only true when those overlapping objects were added to FlxMEM before the object with mouseChildren = false

Example: a sprite group is created and added, with mouseChildren = false. Its children are created and added. Clicking a child will result in both the parent and child receiving callbacks.

Possible solution: this behavior happens due to the unshift() within add(), but changing it to push() wouldn't fix the underlying issue. Perhaps sorting _registeredObjects, with the mouseChildren = false ones coming first, would work. unshift if it's false, push if it's true, and sort/rearrange if setObjectMouseChildren is called.

When two overlapping objects have mouseChildren disabled, it's unclear what should happen.
