* This function is to display the added resources (lessons) in the learning path player and builder

* the two ids are a bit confusing, I admit, but I did not want to change Patrick's work, I was
* building upon it. - Denes
*
* Parameters:
* @param completed - if ="completed" then green presentation with checkbox
* @param id_in_path - if onclick then this lesson will be considered completed, that is the unique index in the items table
* @param id - that is the correspondent id in the mirror tool (like Agenda item 2)
* @param type - that is the correspondent type in the mirror tool (like this is a Link item)
* @param builder - if ="builder" then onclick shows in new window
* @param icon - if ="icon" then the small icon will appear
* if ="wrap" then wrapped settings are used (and no icon is displayed)
* if ="nolink" then only the name is returned with no href and no icon (note:only in this case, the result is not displayed, but returned)
