This commit coverts everything in the codebase to use the new
users_order_by_sql function when sorting lists of users. More details in
the bug.
Note that this does not change places where users are displayed in a
sortable table, and the sort order comes from the table.
Major tasks undertaken in this patch:
* New format_text argument, overflowdiv.
* New page layout Report.
* Review of all format_text calls.
* Added support for the report layout to all themes.
* Changed forum post display from tables to divs.
* class html_component does not exist any more
* class html_table rendered via html_writer::table()
* html_table, html_table_row and html_table_cell have public $attributes property to set their CSS classes
* dropped rotateheaders feature, should be added again after more research of possible ways (<svg> is not nice IMHO)
* dropped possibility to define CSS classes for table heading, body and footer - can be easily done and better done using just table class and context
Please forgive me if I have missed converting any output statements. If you do find an output statement that is not formatting correctly please refere to the table I added to this bug in regards to how it should be formatted.
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
* Display the grouping a course module belongs to on the course page - for course managers only.
* When adding users to groups, display the groups a user already belongs to.
* Added an overview report that shows groupings, groups and members for a course.
* Added a dialogue to automatically create groups and assign members based on either the number of desired groups or the number of desired users per group.
