Force Session Close

While my team was building an extranet application for a client we came across a slightly strange requirement from their InfoSec Audit team.

They want to forcibly log users out who have been active on the site for longer than 12 hours making them re-authenticate.

This is not particularly user friendly - but audit teams tend to not be particularly negotiable about ISO27000 requirements.

I had a look around and couldn't find anything which did specifically this - so I took some time to write my first Drupal module.

If this is helpful then great. Pull requests/patches are gratefully received.
