Fixing the 'does not define the standard capability... addinstance' issue, and version bump.
As described in #68, limits the ability for users to delete quickmail history.

I am unclear as to which role(s) we would prefer to give this capability to.
This commit sets it to the role 'Manager', though 'Course Creator' might be more appropriate.
fixes #65 by causing the list to be sorted by last name.

Depending on the global config for full name display, this makes more or less sense.
Providing a choice in the form would be ideal...this is quick.
