debug message improvements.
work in progress: copy Facebook code from Others Indirect into Facebook rule;
need to debug and remove obsoleted code from Others Indirect.
Added pageSpecificData pass-through, which Facebook should use to detect cover
photo in hover card pop-up to prevent showing profile pic.  Pass ing
or its src from getImageNode to getZoomImage.
facebook: fixed again to not show pop-up over cover image.

The approach now seems to fix some other problems too.
It's a more robust way to show profile pics only over profile
thumbs.

Remaining known issues:
- need more specific URL RE for facebook instead of .*?
- l.php links not working
- Others call into facebook getZoomImage is disabled.
- remove dead code from Others(Indirect) and Facebook rules.
