The following changes have been made in this commit:
1. Renamed the side bar thing to dock, this is consistent through all code/css now.
2. Converted everything to YUI 3 except the panel which docked items are shown in, this iwll be converted once YUI 3 overlay is no longer beta.
3 Redisigned the dock, all blocks can now make use of it, and theme code within JS can override it so they can make it look as they want.
More changes are coming
When logged in there is a my moodle dashboard branch, when viewing a site profile there is a users branch, and when viewing a course profile there the user is shown under the participants branch
this involves moving all formslib includes to where they're actually needed.
it also moves the portfolio stuff from assignment,data,chat,forum and glossary
into a locallib.php which involved creating it for many of those modules.
As requested and voted on admin can now choose not to include course categories within the navbar and global navigation block.
At the same time I also introduced a second setting, showallcourses, which ensures all of the courses a user is registered in are shown on the navigation at all times.
Admin pages were originally skipped over and not added to the navigation, however this means we don't know where in the navigation structure we are on display, now we add hidden pages to the structure and force them to not display.
Added methods that allow a navigation cache to be marked as volatile so that it is destroyed on shutdown, forcing the next page to load to completely regenerate the navigation structure.
Caches are marked as volatile automatically if the load is within the system context, and can optionally be marked as volatile by calling PAGE->navigation->clear_cache() if desired.
Also fixed issue whereby PAGE->set_url was being called by testdeprecatedlib but not being reset to the original value causing several flow on errors through simpletests
* If no active node is found when the navigation is called upon then we attempt to find a best match active node
* Links are now produced with frame breakout actions
* Links ending with / are presumed index.php for matching purposes
Note: I also took the oppertunity to extend navigation_node action handling, so that navigation nodes can accepts
moodle_url, html_link, or strings for actions
