Migrate site to new hosting provider + domain

[noahsbwilliams]

Background

Pending #273, the site currently hosted on Joe's SiteGround account will need to be moved to a new host.

This entails a mysqldump of the database, an scp download of the the site media folder, and a subsequent mysql restore and scp upload of the data to the new host.

Acceptance Criteria

• Database references to old domain are changed to www.progcode.org
• Naked domain to www redirect present
• DNS records flipped
• TLS enforced (301 redirects + HSTS)
