The problem here was that the manifest file was written into the
'./files/leap2a.xml' instead of the './leap2a.xml' in the ZIP package.
I believe there was a bug in the write_new_file() using the 3rd parameter
incorrectly. A detailed review of all other modules using the same
method must happen soon.
The problem was in the order of the content preparing. Now when the
filters are always skipped (they have to) we must always run
format_text() first. That will prepare nice HTML in which we just
rewrite the portfolio URIs.
Note that we are still calling clean_text() so that we do not export
malicious code for portfolios like File download. In the future, this
may be changed, made format specific or even per-export configurable.
As a side product of the patch, I have re-enabled online assignment
portfolio export and switched $options->para to false consistently.
Filters can replace text with images (smilies, temporary TeX images
etc.), links to glossaries or databases or embedded media players.
Therefore it is important to disable filter processing during portfolio
export.
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.
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.
