Still needs some work to:
- Minimise AJAX calls by writing multiple settings at once.
- Move the settings storage/retrieval JS code into a global file
- Avoid using synchronous AJAX calls in the main thread
Modules may now include functions that return lists of menu items
that will be included on the main browser window menu. While we're
at it, move the test views into a separate module.
A user authentication module based on flask-security is added, which
allows users to login and change/recover passwords etc. Custom templates
are included for the user/password UIs.
A new setup script will initialise the user (and later settings) DB,
adding the first user and granting them an Administrator role.
A redirects blueprint module is added to handle simple URL redirects.
A browser module is added and currently renders a skeleton page with
a menu bar, gravatar and jumbotron.
NOTE FOR LATER: Currently this code might make the nice basis for any
web app that needs user management and plugins. Hmmm....
