from htdocs/lang/en.utf8/admin.php to use the Launchpad
bug tracker URL instead of Eduforge and renamed to
uploadcsverrorunspecifiedproblem1.

Also changed the reference to Mahoodle.pdf in the README
from https://eduforge.org/docman/view.php/176/3200/Mahoodle.pdf
to https://wiki.mahara.org/images/d/d5/Mahoodle.pdf
