/**
* @todo Selectable tree with multiselect (toggled via "Batch Actions" panel)
* @todo Fix initial, unnecessary html_data replacement of existing tree (see below)
* @todo Icon and page type hover support
* @todo Sorting of sub nodes (originally placed in context menu)
* @todo Refresh after language <select> change (with Translatable enabled)
* @todo Automatic load of full subtree via ajax on node checkbox selection (minNodeCount = 0)
* to avoid doing partial selection with "hidden nodes" (unloaded markup)
* @todo Add siteTreeHints to field (as "data-hints" attribute with serialized JSON instead of javascript global variable)
* @todo Disallow drag'n'drop when not matching "allowedChildren" or "allowedParents" (see siteTreeHints)
* @todo Disallow drag'n'drop when node has "noChildren" set (see siteTreeHints)
* @todo Disallow moving of pages marked as deleted
* @todo Enforce sitetreeHints rules on page creation ("allowedChildren", "noChildren") -
* most likely by server response codes rather than clientside
* @todo "defaultChild" when creating a page (sitetreeHints)
* @todo Duplicate page (originally located in context menu)
* @todo Update tree node title information and modified state after reordering (response is a JSON array)
*
* Tasks most likely not required after moving to a standalone tree:
*
* @todo Context menu - to be replaced by a bezel UI
* @todo Refresh form for selected tree node if affected by reordering (new parent relationship)
* @todo Cancel current form load via ajax when new load is requested (synchronous loading)
* @todo When new edit form is loaded, automatically: Select matching node, set correct parent,
* update icon and title
