Testing changes after karoshi V10 beta4:

Moodle, owncloud, joomla updated
Moodle - now set to use https at all times. This was causing a problem in the latest firefox with insecure items on the page.
Owncloud now installs with www-data as the owner to allow the inbuilt updater to work.
update_server - will now remove old kernels if called from buildserver.
suphp - now uses suphp.conf from unbuntu 12.04 to stop all php scripts being run by it.
change_management_passwords - now checks to see if mysql is started before trying to change the mysql password. gpp --no-tty changed to --batch.
