Mark toplevel nodes affected by template expansion 

This allows for debugging expansions, which are otherwise confusing and
difficult.  This will be valuable information for the Summary Pages as
well (see future commit).

* src/current/include/preproc/template.xsl (preproc:expand-template): Mark
    toplevel nodes after expansion.
  (preproc:mark-tpl-expansion): Add templates.

<!--
Add nodes describing where the parent node came from.
This helps in debugging and understanding code created by templates.
This isn't the best way, but e.g. enclosing all expanded nodes in a parent
tag causes problems with the rest of the system. Adding an attribute to
the node is an option, but this implementation allows a node to be marked
by multiple templates, should such a thing ever occur.
