(1) This update comments out the line in Logout.pm that transmits
the username to Login.pm if the "Log in Again" button is pressed.
This change is needed to suppress an error message in the Login screen
that would appear if Login.pm is sent a username but no other
credentials.
(2) This update adds documentation to authen_LTI.conf.dist
that was lost when authen_LTI.conf.dist was created, probably
due to an out-of-date version of global.conf having
been used to create authen_LTI.conf.dist.
Added the support for Shibboleth lazy session mode

Ww2.5.1.1 updates from Bill Wheeler
Allow admin course data tables and directories to be updated

This gets rid of strange errors which occur for example when  you
try to delete a user in the admin classlist directory.  The delete command
tries to delete tables and fields that don't exist
Automatically create achievements directories.

If defaults.config file does not
have listings for the achievement directores then nothing happens.
All of these upgrade checks are skipped.

Check that modelCourses has the templates/achievements
and html/achievements directories.  If not then modelCourses
needs to be updated first -- issue a message to that effect.

If the course is missing either the templates/directory or the
html/achievements directory then create it from the corresponding
directory in modelCourse.
Fixes bug 2419: In the case of a single answer blank a student could have the answer only partially correct,
for example where the answer is a list. Although this would be graded correctly with a status strictly between 0
and 1, the student would still see a green bar below the problem stating "Your answer is correct." This fix gives a more appropriate response: "Part of your answer is NOT correct."
