[Untested] ClsLckMgr.onclose -> app.stop, updateWord, typographical quotation marks, duplicate menuUDItem
[Untested] reduce KBStsApp's efforts to know whether UD is built
[tested] Map from the listview's one entry dom element to a word, to avoid unnecessary book keeping and data etrieval from DOM.

It is transitional that we temporarily pass listview's dom elem to edit view. We'll change editview to a dialog (like settings app) returning a promise so it's no longer to receive that DOM element.
