Updates to ATbar

Hi Mark,

I'm Magnus White, I work with EA Draffan in ECS on ATbar and we have significantly improved it since the version used in your Moodle block. I've updated it and change the version number (I hope correctly). ATbar has grown somewhat and now has a host of new services. If you want any custom stuff or different stuff loaded on ATbar I can easily create you a new one as all of it's functions are now plugin based.
