/**
 * Modified version of NpEditThisButton of the Newspublisher extra (Copyright 2011 Bob Ray), 
 * with an additional parameter for specifying the ID of the target resource to be edited 
 * (e.g. for use with getResources).
 * The button can be styled by its CSS class (np_edit_this_button)
 * example: [[!NpEditThisButton?id=`5` &np_id=`2`]]
 * 
 * @property $npId (int) - ID of newspublisher page (set automatically on first run).
 * @property $id (int) - ID of resource to be edited
 * @property $noShow - Comma-separated list of IDs of documents
 *      on which the button should not be displayed. Defaults to
 *      home page, and NewsPublisher page.
 * @property $buttonCaption (optional -- not actually a parameter) -
 *      Caption for edit button.
 *      Defaults to np_edit language string or "Edit" if empty.
 * @property $language (optional) - Language to use for error messages.
 * @property $debug (optional) - Displays the button on all pages with
 *      either the $buttonCaption, or a message explaining why it
 *      would not be shown.
