added mailer and started on user add and manage departments

currently working on finishing up adding of users.

we already have managing of departments - but what we need from an
admin view is the list of departments, and then the listing of users in
the department.  from there we need the users roles and levels.

from there we need to have an admin add roles to users - probably
seperate add user form for each and also add users to departments.
those with director roles will get the admin level and those without
will get default waiting to be assigned level.
