Makes autocomplete entries focusable, supplies the <li> elements with proper keydown handling, and adds a focus() call to <gr-cursor-manager>. This focus() call is optional, enabled by the 'focus-on-move' property. Bug: Issue 4281, Issue 4279, Issue 5321 Change-Id: I944350090ccb240bde6302f0aba8f2585172f5df
