Debugging on dev version with prod db
Forgot to delete the update state line..
Erasing debugging trace
Proper state to new affectation
Added button 'Nouveau Client'
Few minor changes
Pushing to prod
Removed supervisors affected in current affect from list of
  available supervisors and vice-versa.
Get get_first_not_affected to work with other date than today
* Pushing to prod
Polished two way binding of chief supervisor and
  the list of supervisor elements so adding an elem to one removes it from
  the other.
