Heroku-ready version of Staytus

[ideasasylum]

First: This is something of an experiment rather than a PR that can be merged.

I wondered what it would take to make Staytus deployable to Heroku using a Heroku Button. It came down to:

• Use Postgres: replace the mysql gem with pg; change the adapter in database.yml, remove the mysql-specific options from schema.rb
• Add an app.json file specifying the default Heroku formation, config variables, etc.
• Add the Heroku button to the README

You can try the Heroku button here in my fork's README

I've got no interest in maintaining a Heroku-specific fork, and I'm not even sure I have a use for Staytus right now, but I wondered if there was a way to have a single repo with both mysql and postgres dependancies? I'm not sure how this would work. Could an environment variable change which adapter is loaded? But how do we keep schema.rb database-agnostic?

Maybe some other interested and knowledgeable parties will find this and comment.

I'm running your fork on Heroku... and it's working well (except e-mails)! 😄

is this merged? if not, any reason?
