User Story:

As an editor who uses the visual editor to edit pages, I would like to be able to easily add existing labels to a page during the "publish changes" stage, so that I do not need to manually add labels elsewhere.

Acceptance criteria:

• A new MultiselectLookup field is present in the publish changes dialog, with which it is possible to autocomplete on any of a user's watchlist labels.
• There will be a hyperlink from there to Special:WatchlistLabels.
• Any number of labels will be able to be selected.
