Form element 'header' used to be used for rendering the page contents.
This led to layout problems in non-gecko browsers. This patch fixes the
issue by using raw 'html' element to render the page contents.
That rendering method should not use cell style attribute at all.
Instead, the alignment should be controlled by CSS. However, this will
require more massive changes in the Lesson code to be done by the module
maintainer. As a temporary fix, left alignment is set as it usually
matches the layout that students see.
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.
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.
