=== Current version: ##2.1## ===
~-added "Hide source" button, as per NilsLinenberg's suggestion;
* 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 users 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
* it with an existing skin, or restore the default settings. Wikka
* 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.
* @version 2.1
* @since Wikka 1.1.6.X
* @output displays a form for selecting alternate skins and edit
* @todo - store custom skin in DB;
