Edit user fuctionality is implemented.  For a user, click on their email
address after logging in to change their password.  For admins, click on
their name in the submissions list or search for their name in the
"Search by user" box.  Still a few bugs I need to work out(regarding
password validation).

Bugs:
 User passwords should be checked to make sure they fit the standards
 autofill on search box causes you to redirect to index.jsp for some
reason.
