Schema change - Work study

[David Burke]

alter table work_study_workteam_login change column user_id workteamuser_id int;

This and revision 03d3edc502be fixes a potential security issue where work study users can escalate privileges. I'm deploying on production sites now.

Also I should state clearly this requires manual cleanup of work study user permissions. Work Study users should probably have edit user (or superuser) privileged revoked. Then add Can add/change/delete work team user perms. 

But for schools who only use work study it probably doesn't matter.
