[Emacs-orgmode] third export request

[Austin Frank]

Last one on this topic, I think :)

I don't know if this is more of an org-export or an org-publish request, 
but I'd like to be able to do something like

    (setq org-export-as-ascii-directory "~/notes/text/")

and have any org-export-as-ascii files sent to that directory.  Likewise 
for the other org-export-as-* functions.  It'd be nice to be able to 
configure where the ical files end up when they're exported, as well.

Allowing exports to be written to specific directories seems like it 
might provide a sensible default for the :publishing-directory plist 
entry in org-publish-projects-alist, but I admit I haven't thought that 
through very thoroughly.

Thanks again for reading,
