Bugzilla – Bug 17270

It seems Opera/WebKit/Gecko/IE don't support MutationNameEvent. Since there is MutationObserver now, please give MutationNameEvent the bullet.
Additional reason: It was not in DOM Level 2 Events.
Agree. I don't think there's any need for MutationNameEvent to continue to exist. I removed it from the spec along with all references to it.
