org-odt.el: Export TOC max-level information.

The TOC max level which could be specified by user is lost during the
export operation. However, this information could be useful in particular
with the ODT exporter. So if another script work on the ODT afterward and
ask to re-compute the TOC, the new TOC will keep this max level.

TINYCHANGE.
