(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due to an out-of-date version of global.conf having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.
OPL-update missing tables, update check_modules.

OPL-update's backward compatibility feature with NPL couldn't find the
table names due to some typos and a %tables that went out of scope too
quickly.

Looks like there are now new Perl modules required. Added the
HTML::Template and JSON modules to check_modules.pl.

Also fixed typo in localOverrides.conf.dist which made %showeditors
problematic.

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.
