Onboarding tweaks (#272)

* Small fix to side menu rendering

* Change onboarding to use an explicit 'is onboarding' mode to more clearly control the flow

* Add a progress bar to the welcome banner

* Dont show the 'unfollow button' on posts in weird times (close #271)

* Improve the empty state of the feed

* Only suggest recent posts
