Update jQuery Cookie to v1.3.1

Source

* https://github.com/carhartl/jquery-cookie/blob/v1.3.1/jquery.cookie.js

Change log

* https://github.com/carhartl/jquery-cookie/blob/v1.3.1/CHANGELOG.md

Notable changes:

* Removed the "raw" option from $.cookie.
  This can now only be set globally via $.cookie.raw

* Bugfix: Properly handle RFC 2068 quoted cookie values.

* New: $.cookie() returns all available cookie.

We should eventually upgrade to v1.4.1, but that has a breaking change.
Namely, it drops support for $.cookie('key', null) which needs to be
replaced by $.removeCookie which didn't exist until v1.2.0.
