Add a get_participants method to Team
To remove problem saving new reviews, check to see if AssignmentQuestionnaire
is nil, & if so, don't dereference it.  (Kind of a hack, but works for tonight.)
Remove the call to on_keyup that was logging us out whenever we
edited a questionnaire.
Merge branch 'production' of github.com:expertiza/expertiza into production
Use team_assignment? method instead of checking max_team_size.
Add script for changing max_team_size from 0 to 1
Merge branch 'production' into staging
