[O] [ANN] Substantial changes to sitemap generation

[Nicolas Goaziou]

Hello,

I just pushed a revamp of sitemap generation during publishing process.
If you tweaked sitemap, you almost certainly need to update your
settings.

Basically, the changes at the property level are:

  - :sitemap-sans-extension and :sitemap-file-entry-format were removed
  - :sitemap-function changed its signature
  - :sitemap-format-entry was added

Also, the patch set implements the following function

  `org-publish-find-property'

See `org-publish-project-alist' for details (or the manual).

Feedback welcome. Ideally, if it is better, we might want to propagate
the same kind of change to index generation.

Regards,
