Pre-release 0.3 after some cleaning up of a long-dormany repo:

- removes broken things (views dependent on external results to render), friendly_id
- rspec tests for the User model, and working on controllers
generate mailer creates spec
why aren't those changes here?
somethings up with git flo
adding quiet_assets (again?)
html and txt templates, synchronous delivery
letter-opener doesnt work with vm, maybe time to ditch vagrant
enviro vars with figaro
mail is go!
come back to testing
Merge branch 'feature/welcome-email' into develop
