[Orgmode] patch for :index-title

[Manuel Hermenegildo]

Hi Carsten,

:index-title (which I need) was not working and I saw that the
implementation was not there yet in the (git) code, so I added it to
org-publish-org-index (hopefully correctly). I send you the diff and
the new version of org-publish-org-index.

Btw, a minor thing I noticed in the manual: in the documentation for
org-publish-project-alist it says:

  "The :include property may be used to include extra files. Its value
   may be a list of filenames to include. The filenames are considered
   relative to the publishing directory."

I think it should say "base directory". 

Cheers --Manuel
