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.

These tests did not cover the classes that should have been
automatically applied to the dropdown based on the space around it. Now
they both test that the dropdown should be facing down, because there is
enough space below it to display the dropdown.
Previously the tokenizer only worked when creating multiple options
at once if all of the options existed. It always worked when creating
a single option, because all of the special cases were handled by the
tagging module. When working with multiple options, the tagging
module does not kick in until after the query has been run, which
is when the tokenizer does its magic.
This fixes the issue by automatically creating the option tags that
the tagging module would normally create. It only does this if the
options do not already exist, so we don't need to worry about the
tokenizer creating duplicates of existing options.

The error handler should not be raised if a request is aborted while
another one is sent out. This attempts to detect those cases by
handling the case where the error was raised and the request has a
status code of 0, which should either mean we're in offline mode or
the request was aborted.
