My Moodle MDL-19124 New version of My Moodle, User profiles and Course profiles, all with block support

Thanks very much to Remote Learner Canada, especially Hubert Chathi and Olav Jordan, for their work on the bulk of this code, and also Mike Churchward for supporting them.  I worked on it after that (actually simplified it by removing a feature temporarily: multiple pages) to bring it more to what I was imagining, and to provide a base to build on and get all the navigation perfect.

There's still work to do.  Some blocks don't quite work as expected, and some of the code still needs upgrading to bring it fully into line with 2.0.  We also could use a much better course overview block and better CSS styling of the profile pages.  But it's definitely more usable this it was, I think.
