After we upgraded to QUnit 1.23.1, we gained support for
assert.expect(). This allows us to guard against any race conditions
within tests, because now expect() will be linked to the specific test
instead of the current running test.
Select2 will now automatically update the selection if there are options
added to or removed from the DOM within the `<select>` element. This is
supported in all browsers except for Internet Explorer 8. Internet
Explorer 8 does not support the DOM mutation events which were added in
Internet Explorer 9, and it does not support mutation observers which
are the recommended way of handling this in modern browsers.
DOM mutation events also trigger for the `<select>` itself when it is
pulled from the DOM, so we need to filter these out within the event
handler.
Despite supporting mutation observers, we cannot accurately detect if
the removed option was selected at one time or another, so we need to
always re-pull the selection when an element is deleted.

This was required for us to get assert.async() support within tests, as
well as assert.expect() support. This was required because we need them
for multiple async tests that are coming.
Previously we hacked around the infinite loop between closeOnSelect and
selectOnClose by attempting to detect what event was being triggered
without knowing what event triggered it. Now we properly relay the
Select2 event and the jQuery event that triggered the select or unselect

This will include the event type in the _type property, so it can be
accessed within the event handlers if it's not normally passed in. This
should not conflict with any existing handlers, and this should not be
considered a public property on event arguments.
This will make it easier in the future to test that we support labels,
and it tells people who are looking to confirm that we support labels
that we in fact do.
This adds basic support for focusing the Select2 element by triggering
the `focus` event on the underlying <select> element. This implicitly
adds support for <label> elements, which will trigger the `focus` event
on the `<select>` if it is clicked.
This also fixes the focus issue that previously existed if Select2 was
opened while in a <label>. The focus would be transferred to the search
dropdown, and then immediately pulled away to the <select> element. This
happened because the <label> element triggers the `focus` event when a
`click` event propagates its way up, and we do not stop the propagation
of the `click` event when it is triggered on the selection.
