This achieves a massive clean-up. It simplifies comples code in a number
of places. It allows some methods and functions to be moved to a more
appropriate home (for example cannot_review_message to the quiz class).
It moves more logic out of the renderer.
The problem was when output was being started in relation to when the fake block was added.
Took the opportunity to clean up the quiz renderer API a bit.
I added a deprecated method add_pretend_block that forwards to add_fake_block, so old code should be break. However, I aslo updated all the callers in core code.
* Routine navigation through the quiz and question modules
* Fixed navbar through quiz and questions
* Pages headers added throughout
* Added method to turn a navigation node into a tabs array suitable for use with print tabs
This was implemented by Matt Petro of the University of Wisconsin - Madison Engineering
School and Math Department. Many thanks. Reviewed by and committed by Tim Hunt.
This adds a new Overrides tab to the UI, with sub-tabs Group overrides and User overrides.
Each of those lists all the overrides that currently exist, and lets you manage them and
create more.
When a quiz is being attempted, the override that applies to the current user is combined
with the current quiz settings loaded from the quiz table (normally called $quiz).
If there are both user and group overrides, then just the specific user override is used (more specific).
If the user is in several groups, then the overrides are combined to give the most permissive set of options.
There is one new database table quiz_overrides, to store the overrides.
At the same time I have converted the calendar block to use YUI instead of overlib, this introduces one regression in that the panel is shown immediatly but should really have a minimal delay for usability.
This will be fixed once the theme changes for 2.0 have been commited
The code to print blocks in now in theme layout.php files. (Or in
moodle_core_renderer::handle_legacy_theme)
Code for printing blocks everywhere else has been stripped out.

The way the HTML for a block instance is generated has been cleaned
up a lot. Now, the block_instance generates a block_contents
object which gives a structured representation of the block,
and then $OUTPUT->block builds all the HTML from that.
How theme config.php files specify the layout template and block
regions by page general type has been changed to be even more flexible.
Further refinement for how the theme and block code gets initialised.
Ability for scrits to add 'pretend blocks' to the page. That is,
things that look like blocks, but are not normal block_instances.
(Like the add a new block UI.)
Things that are still broken:
* some pages in lesson, quiz and resource. I'm working on it.
* lots of developer debug notices pointing out things that
need to be updated.
