annotate comments/models.py @ 917:0365fdbb4d78

Fix app conflict with messages. Django's messages app label conflicts with our messages app. We can't easily rename our label as that will make us rename database tables. Since our app came first we'll just customize Django messages label. For Django 1.7.7 upgrade.
