Patch makes user dashboard respect permission overrides
that have been set on individual blocks on the system
dashboard (indexsys.php). When a user dashboard is created
either when the user visits their dashboard for the first
time or after an admin reset. When blcoks are copied to
the new dashbaord overriden permissions are also copied.
If the default dashboard contained a block that was missing from disk
then "Exception - Call to a member function instance_copy() on bool"
was shown to users. This change only shows an error with debugging
enabled which now includes the name of the missing block.
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.
