Patch 5.3.0/API changes

== New Features ==
* You can now control for which specialization you will receive loot from LFR/Quests.
* The number of pet stable pages has increased from 2 to 5 (Increasing the number of slots from 20 to 50).
* Knowledge base and GM tickets now use an embedded web browser to interact with Blizzard's Support website.
** The embedded browser functionality is encapsulated by the Browser widget type.
== Misc Changes ==
* tradeSkillLink encoding changed significantly. The first four fields were re-arranged, and specialization data was added for Cooking.
== Bugs ==
* If (panel) is called before the addon panels list is updated after adding a new panel, the interface options frame will open to another panel. You can work around this behavior by calling the function twice.
