Making the profile page tabs work in responsive design (bug #1253835)

Because the profile tabs are created on the fly by javascript in
htdocs/artefact/internal/js/profile.js (which is mochikit) after the
page loads I couldn't use the exact same trick as other places in site.

Insetad I had to add the necessary dom elements and onclick toggle to
the tab block as they were being created.

And then got htdocs/js/rd-nav.js to check for the existance of profile
tab set and if exists deal with it like the others.

I also discovered all the instances where TABS heading was used
happened to be a hardcoded string so tidied that up also
