Extension:StalkerLog

The StalkerLog extension adds a log type that keeps track of user logins/logouts.

Configuration
By default the log is viewable to all, but can be restricted with the  role, assignable via $wgGroupPermissions.

Changelog

 * v0.6 - (r41476,r41477) Made it fail more gracefully on MW 1.11 and 1.12, which didn't have the $oldUser parameter yet for UserLogoutComplete. Thanks to maeck on IRC for pointing this out.
 * v0.5 - (r38240) Basic functionality, etc. Copied from my development copy at work.
