[Orgmode] Patch for Sitemap: org-publish-org-index

[Sebastian Rose]

Hi,

the creation of the sitemap was not working for my project when publishing.

There were two bugs:

* The title of the page was made from index-file-name and a broken link.
* When publishing recursively, the links to files were not working 
(missing relative path)

The appended patch (in horror-lisp :-) fixes these two bugs. I diffed 
against the current git version (using 'git-diff lisp/org-publish.el').

Additionally subdirectories get an extra link with a '/' appended.
The files and directories in subdirectories are indented, so the tree 
structure of the published project is visible.


I know the code looks terrible, but it works just fine here.


Regards,
