Focus on source XML manipulation, introduce indexes

Instead of XHTML or Atom, so resulting files get generated out of
custom XML structures now.

This was needed to get indexes that won't depend on Atom (and to avoid
the duplication).

Now indexes can be included with something like the following:

<notes xmlns="" number="5"
       src="../build/notes-by-modification-date.xml" />
