Security started: now list page available for all except student;
Also now our roles should look like: "ROLE_STUDENT", "ROLE_SUPERADMIN", "ROLE_CURATOR", "ROLE_FEEDBAKER", "ROLE_OFFICE". Also an employee may have more then one role, so they should be separated  by ';' iin DB column, so add function "addRole" to User class.
