org-info.el: Generate HTML links to gnu.org 

* lisp/org-info.el (org-info-export): Convert info links to HTML URL's
that point to appropriate gnu.org or other pages.  User's can customize
the behavior using `org-info-emacs-documents' and
`org-info-other-documets' new variables.

*** =ITEM= special property returns headline without stars
*** Rename ~org-insert-columns-dblock~ into ~org-columns-insert-dblock~
The previous name is, for the time being, kept as an obsolete alias.
*** Function ~org-info-export~ changes.
HTML links created from certain info links now point to =gnu.org= URL's rather
than just to local files. For example info links such as =info:emacs#List
Buffers= used to be converted to HTML links like this:
: <a href="emacs.html#List-Buffers">emacs#List Buffers</a>
where local file =emacs.html= is referenced.
For most folks this file does not exist.
Thus the new behavior is to generate this HTML link instead:
: <a href="http://www.gnu.org/software/emacs/manual/html_mono/emacs.html#List-Buffers">emacs#List Buffers</a>
All emacs related info links are similarly translated plus few other =gnu.org= manuals.
