Title: Convert badges over to using the Javascript Issuer API (Fixes #361)

- download links now call the OpenBadges Javascript Issuer API to issue the badge
- significant updates bin/badge.py to only produce JSON assertions
- email addresses are now hashed in assertions
- deleted the badge images and added assertions with salted emails.
