FIX: You need to be logged in to edit wiki posts.
UX: Don't highlight the latest poster in the topic list if there is only
one avatar shown.
FIX: moving a post to a topic with a deleted post should use correct post_number. Was getting unique index violation on (topic_id, post_number).
TWEAK: Don't include moderators on "About" if they are admins.
FIX: do not rollback imports unless data has been changed
FEATURE: backup without uploads
TRIVIAL: do not remove backups in development
FIX the build
FIX: user avatar in flags list
disable digest emails when importing a forum
FEATURE: add an alert in sidekiq's scheduler tab when sidekiq is paused
UX: Move topic entrance widget to posts column
FIX: Moving posts was not updating `reply_count` and
`reply_to_post_number` so reply linkage was broken.
