Title: Set release information in Heroku environment

Update the application configuration on every deployment and set a special
RELEASE environment variable to the line from the current release from the
output of `heroku releases` which contains date, author, sha and time ago in
words.

An application might read such information and show it in the GUI somewhere.
Of course, it would have to parse the message itself.
