Set 'control' attribute for item box fields

Browse source 
Set 'control' to the id of either the value label or the textbox,
depending on whether the field is being edited. This causes NVDA to read
the label associated with the textbox, but seemingly only the first time
it's selected.

Unfortunately NVDA also does some other unpleasant things, like reading
a description from the duplicate-merging pane, which isn't the active
element in the deck, and reading the entire text, including all field
labels, of the item box) I'm not sure how much we can improve this until
we're on Electron.

VoiceOver doesn't read the textbox's label either, even though it does
so in the bookmarks window in Firefox. Maybe things have improved since
Firefox 52, so we can text again after upgrading to Firefox 60.
