This change will hide the setting "Require that students accept the submission statement" at
the assignment level if no submission statement has been configured for a site. It also includes a
change to the help text to separate the assignment level setting from the site level setting. This
change also sets a default assignment submission statement.
AMOS BEGIN
CPY [requiresubmissionstatement,mod_assign],[requiresubmissionstatementassignment,mod_assign]
AMOS END
This adds separate controls for the sending of notifications from the mod_assign.
The separate notifications are: student submission receipt (for students), feedback available (for students)
and submission updated (for graders). The grader notifications can be enabled for all submissions or just late ones.
Added code to reset the message providers on upgrade (only applies for a 2.3 dev version)
