Title: Fixed position tooltips popovers

I've added support for fixed position popovers and tooltips via an additional "fixed" parameter which may be passed tooltip options object on init. Defaults to false. If true, a "fixed" class is added to the element.

PS this is my first pull request so please let me know if I'm doing it right :-)

Cheers
Dave
