Accounts - Added basic registration/login interaction with DB.  Secured with salted hashes.
Integrated basic registration and login to the main demo page.  The password is nicely hashed and salted.
Integrated further with sessions being logged.  An account settings page and a functional log out button appears.
Got responsive country/region/city select boxes working.  Will work with coordinates next.
Account settings now recenter the map.
Altered map to display the latest instance of each satellite, removed unnecessary account files.
