indexing: start of Indexing Export impl. based on (X)HTML export

This adds a indexing output/export to HTML code, which will output
a xml document that will be used for indexing of the document. It
is based on HTML to reuse the traversal through the doc. model.

It is enabled by setting the "IndexingOutput" export parameter.

This commit only adds in the groundwork, but the output is still
more or less the same as html and the follow up commits will
add more indexing specific changes. The only change is to use
"indexing" as the top level element and the document is a valid
xml (has the xml header).

Also add basic test that the indexing output/export works and
can be parsed as an xml with "indexing" top level element.
