Converted the pinned applications selector to a typeahead.
Summary: Fixes T11513. Previously the selector was just a giant dropdown which was just... just too much. Now there's a handy typeahead.
Go to Settings -> Home Page -> Pin Application, start typing in the form then select one of the options. Click on "Pin Application". The application should now be in the list.
- Type nothing into the box and submit, nothing should happen.
- Choose an application that is already pinned. The list should stay the same.
- Type nonsense into the box and submit, nothing should happen.
