select2/dist/js/select2.amd.full.js
Kevin Brown e16c505c25 Move to a central key handler
This allows for any control to emit key events, and for the Select2
instance to handle them. So now the search box will allow for
results to be scrolled and selected, bringing back the old expected
functionality. This also stops triggering new queries when the
arrow keys are pressed.

The container will also be automatically focused when the dropdown
is closed, which is consistent with the old Select2.

The results will no longer be queried on initialization, but
instead will be queried when the dropdown is opened. This is more
consistent with the previous version of Select2.

The search box will now be cleared when the dropdown is closed.
