* Reworked flow to better grant the 2FA to non-enabled users on the wiki access. This should prevent users from being hit up with a 2FA challenge just after enabling the software on the wiki or just after configuring their first provider.

* Added LogLog support to this module.
* Refactored workflow to eliminate redundant calls and provide cleaner logging.
* Rewrote the login function to (properly) use a cookie to survive a session purge.
* The login cookie now has a server-side timeout setting.
* Added audit/debug logging. The audit logging will provide enough logging without LogLog to track user login activity. The debug logging will help me assist when others have problems.
* Removed trailing spaces.
* Added language internationalization for many options including email notification of successful login option.
