Penny started this work but I'm taking up the rest of it, so there's some changes to how certain things work that I made while trying to understand the way the migration works.

Also commented everything.

Next work - test the PPAE migration, then on to the other templates.

Check for identicality when setting values, that way '' and 0 are not treated the same and thus not changed properly.

Given that that transaction level counting is now implemented, there's no reason to do it ourselves when committing artefacts.

Make sure the attachment list table stays below any content in the blogpost, regardless of how that content is floated.

A couple of checks to make sure that having blocktype code running when blocktypes aren't installed doesn't kill the admin section completely.

old fix fails for apostrophies

made a string translatable

This will hopefully reduce the temptation to use easily guessable usernames
and passwords.

There are two files in /etc/mahara: config.debconf.php and config.php.  Both of these have symlinks in /var/www/mahara.

config.debconf.php is managed by debconf and is overwritten everytime the package is reconfigured.  It is not marked as a config file.

config.php includes config.debconf.php first in order to allow users to overwrite the debconf settings.  It is marked as a config file so that it's not overwritten automatically at configure time.

Changed all requires.
Also removed not used json/renderartefact.php

Rather than (the only example was artefact) lib/artefact.php which is non standard

Add support to the artefact chooser for a 'search' tab that allows drilling through the artefacts that can be chosen.

It works in firefox fine, and works without javascript fine (therefore it works in ie6). Opera also works. Konqueror and IE7 do not work properly.

Add a two character prefix to each log line, that remains the same over the lifetime of the request. This makes it easy to distinguish lines between requests that happen at the same time.

Broke rewriting one pagination link out into a separate method, so it can be used outside this class.

allow public views setting now prevents adding and using public views

changed stylesheet so initials table no longer has a width
=> letters no longer wrap

fixed the upgrade - I have just commented this out for now because I'm pretty sure that blocktypes install themselves separately, not as part of the artefacts
