As jQuery 1.7.2 is the lowest version of jQuery supported by Select2,
it makes sense to run the tests on it. For the most part, we can
assume that the newer versions of Select2 are backwards compatible
enough such that this isn't an issue.
The recommended version of jQuery to use is the latest though, which
is why the jQuery file is only included in the tests.
This revealed a few issues with our data fallbacks and `.append`
functionality that was introduced in jQuery 1.8.
The search box previously displayed a clear icon on the far right
side in webkit-based browsers, specifically Chrome and Safari. This
hides the clear icon in those browsers, and also fixes a slight
sizing issue, so it should no longer be displayed.
This also disables autocorrect, autocompleted, as well as a few
other automatic search corrections on the field, so mobile devices
should have a better experience.

This is needed to escape any bad markup that is passed through
user-entered data. Users can prevent their markup from being
escaped by using a no-op `escapeMarkup` function.
