/**
 * Right Context Menu configuration
 *
 * Some usefull variables:
 *   node.hns = headpage id;
 *   node.isdir = node is namespace;
 *   node.dokuid = the DW id (namespace parent in case of headpage);
 *   id = the DW id of the selected node (headpage id in case of headpage);
 *   index.config.urlbase = Url Base;
 *   index.config.sepchar = Url separator;
 *
 * HOWTO EDIT:
 *
 * To override menu entries or add a menu entry:
 *  - PLEASE EDIT ONLY the scripts/contextmenu.local.js file
 *  - DON'T EDIT this file, it is overwritten at plugin update
 *
 * Base structure of the context menu is displayed below.
 * The entries with 'pg' are shown for page noded, these with 'ns' only for namespaces.
 *
 * Current available for everybody:
 *   indexmenu_contextmenu['all']['pg']['view'] = [...array with menu description here... ];
 *   indexmenu_contextmenu['all']['pg']['edit'] = [ ... ];
 *   indexmenu_contextmenu['all']['ns']['view'] = [ ... ];
 *
 * Current available for admins:
 *   indexmenu_contextmenu['pg']['view'] = [ ... ];
 *   indexmenu_contextmenu['ns']['view'] = [ ... ];
 *
 * Current available for authenticated users:
 *   indexmenu_contextmenu['pg']['view'] = [ ... ];
 *   indexmenu_contextmenu['ns']['view'] = [ ... ];
 *
 * A menu description may contain four kind of entries:
 *  - section title: array with one entry e.g.:
 *      ['Section title (html allowed)']
 *  - menu action: array with two entries e.g.:
 *      ['Title of action 1 (html allowed)', 'javascript here ... see for examples scripts/contextmenu.js']
 *  - menu action with custom tooltip: array with three entries e.g.:
 *      ['Title of action 1 (html allowed)', 'javascript here ... see for examples scripts/contextmenu.js', 'Customized title']
 *  - submenu: array with two entries where second entry is an array that describes again a menu e.g.:
 *      ['title of submenu (html allowed)', [ ...array with menu actions... ]]
 *
 *
 *  Examples:
 *  A menu description array:
 *   ... = [
 *           ['section title'],
 *           ['title of action 1', 'javascript here'],
 *           ['title of submenu', [['title of subaction 1', 'javascript here'], ['title of subaction 1', 'javascript here', 'Click here for action']] ]
 *         ];
 *
 * To Override the common menu title:
 *  indexmenu_contextmenu['all']['pg']['view'][0] = ['customtitle'];
 *
 * To override a menu entry, for example the menu title:
 *   indexmenu_contextmenu['all']['pg']['view'][0] = ['Custom Title'];
 *
 * To add option to page menu:
 *   Array.splice(index, howManyToRemove, description1)
 *     index = position to start (start counting at zero)
 *     howManyToRemove = number of elements that are removed (set to 1 to replace a element)
 *     description1 = array with menu entry description
 *     -> optional: description2 = optional you can add more elements at once by splice(index, howManyToRemove, description1, description2, etc)
 *
 *   indexmenu_contextmenu['all']['pg']['view'].splice(1, 0, ['Input new page', '"javascript: IndexmenuContextmenu.reqpage(\'"+index.config.urlbase+"\',\'"+index.config.sepchar+"\',\'"+node.dokuid+"\');"']);
