doing the heroku deploy

don't pull this in, just use for reference on the issues that came up deploying to heroku 

1) mailcatcher gem requires sqlite, so it can't be in the production group
2) install secrets with alex's gem - remembering to grab heroku secret key base with heroku:config and add to your secrets production group https://github.com/alexpeattie/heroku_secrets
3) for mail to work install the sendgrid addon, and ensure to add the sendgrid email config in production.rb - https://devcenter.heroku.com/articles/sendgrid
