* @author Lars Kneschke <lars-AT-kneschke.de> original code in felamimail
* @param array $_folders array of folders: pairs path => node (string label or array with keys: label, (optional) image, (optional) title, (optional) checked)
* @param string $_selected path of selected folder
* @param mixed $_topFolder=false node of topFolder or false for none
* @param string $_onNodeSelect='alert' js function to call if node gets selected
* @param string $_divId='foldertree' id of the div
* @param string $_divClass='' css class of the div
* @param string $_leafImage='' default image of a leaf-node, ''=default of foldertree, set it eg. 'folderClosed.gif' to show leafs as folders
* @param boolean/string $_onCheckHandler=false string with handler-name to display a checkbox for each folder, or false (default)
* @param string $delimiter='/' path-delimiter, default /
*
* @return string the html code, to be added into the template
