/**
* Allows users to select alternate skins and to edit their custom skins.
*
* This action allows the user to select a skin among those available in
* the Wikka css folder. A form allows to display the markup of each skin.
* Registered user can create it and modify their own custom skin. The
* first creation of a custom user skin consists in the generation of a new
* css stylesheet containing the default wikka CSS settings (as specified
* in the Wikka config file) and stored with the name of the user. Once a
* custom user skin exists, the owner of the skin can modify it, overwrite
* it with an existing skin, or restore the default settings. Wikka
* administrators have write access to all the skins.
*
* Cookies must be enabled for the selector to work and the css folder must
* be write-accessible to the script in order to read, edit and save skins.
*
* @package Actions
* @name MySkin
*
* @author {@link http://wikka.jsnx.com/DarTar DarTar}
* @version 2.2
* @since Wikka 1.1.X
*
* @output displays a form for selecting alternate skins and edit
* custom user skins.
* @todo -integrate with UserSettings.
