[O] Blog-like sitemap for org-publish

[Jon Anders Skorpen]

Hi.

I have made a function which creates a blog-like sitemap. It works as
an alternative sitemap function to org-publish. The second commit adds
a list of blog entries by year and keyword. The commit-diffs can be
viewed here:

Some of the functionality is overlapping with code in org-publish. To
use it simply set :sitemap-function to org-blog-export. It is similar
to the default sitemap function, but :sitemap-file-entry-format and
:blog-entry-format is semantically different.

I hope this can be of use to others, and I therefore submit it here
for comments and feedback, and maybe eventually inclusion. My main
question is what kind of copyright notices should be at the top of the
file? Some parts of the code is almost verbatim from
org-publish. There is also no license information at the top yet.

I am open to signing copyright assignment to FSF if at some point
someone thinks it should be merged into org-publish, but it can also
live happily in contrib/.
