OCIAL-231 FIX Enable tooltips (for links and images)

Added the necessary plumbing to get link_hovered events from the webkit plugin through to the viewer UI.

This requires a llqtwebkit library built from revision 1799a899e06d or later in http://hg.secondlife.com/llqtwebkit to function.  The viewer source changes are backwards-compatible with earlier versions of llqtwebkit, it just won't see any link_hovered events with previous revisions.
