Remove useless length limit on Group#lastname
Monkey patch Group before it is even loaded from standard dir so that db:migrate work (I want to kill myself now..)
Delete our test data before running Group specs
Ensure organization's name is present and unique
Don't extend users.lastname column in test env (it breaks one unit test in core otherwise...)
Fix our ugly Group patch to avoid 'superclass mismatch' errors ; now it's triggered only in rake migration tasks
Rewrite Project#users_by_role_and_organization so that it doesn't rely on Project#organizations association, which will be dropped sooner or later
Improve styles for default members management view in project settings
Sort members by group in projects/settings/members view
Add a visual indicator that a user is member of a project through the group above
