[PATCH] Append value of #+HTML_LINK_HOME to links relative with paths

Hi all,

the attached patch appends the value of #+HTML_LINK_HOME
to links with relative paths in the HTML export.

I need this for RSS feeds, in which relative paths are not
allowed.

This should not break anything, but I'd be glad if someone
can test this heavily against his HTML publishing setup.

Thanks!
