The following are notable changes made in this commit * Lesson page type are now class based and extend an abstract class. This includes a class for the page type and a class for the creating/editing a instance of this page. * Converted all forms to mforms * Action script located in mod/action/* were worked into the above so far less switch statements and the action directory will be removed. * Implements a custom renderer * Converted everything to use page, output, and custom renderer methods * Replaced all deprecated methods incl. print_textarea conversions * Tried to cut down on excessive DB calls. Things worth noting: * The focus of this patch was on cleaning up the module not rewriting it, as such I have organized NOT rewritten. There are still many areas in the module where the code could be greatly improved however to do so would require a rethink/rewrite
