[Orgmode] suggestion: HTML frames option

[Ilya Shlyakhter]

It would be good if the HTML exporter had an option to create a web
page with two frames:
in the top frame would be the original exported HTML, and in the
bottom frame would display
the targets of all external links in the org file.  Within-orgfile
links would still be shown in the
top frame. Then, the org file could serve as an "index" for organizing
a variety of information, and
one could browse the org file in the top frame and quickly see the
targets of external links
in the bottom frame, without having to switch tabs or windows in the browser.

There would be an option to have the index on the left, instead of on the top.
