Wikifeatures diable dialog

I just noticed that for features in Labs include the number of wikis that the feature is enabled on, in the H3. The problem is that the text of the H3 was being used as the title of the disable modal. "Disable The New VisualEditor Active on 1,002 wikis?" was a pretty scary message. This will change the modal to once again read: "Disable The New VisualEditor?"

Also, atomic commit for JSCS conformance.
