new ODF numbered list parameter loext:num-list-format

Instead of style:num-prefix and style:num-suffix new list format
is much more flexible for storing list multilevel numberings.
Now it is possible to have not just prefix/suffix but any random
separators between levels, arbitrary levels order, etc.

Internal LO format for list format is changed: instead of placeholders
like %1, %2, etc we right now use %1%, %2%... Reason: for ODT documents,
having more than 9 levels there is ambiguity in "%10": it is "%1"
followed by "0" suffix, or "%10"?

Aux changes:
* removed zero width space hack: since format string is always defined
this hack is interfering with standard list numbers printing
(see changes in ooxmlexport14.cxx, ww8export3.cxx tests)
* changed cross-references values to lists: they are now including full
list label string: previously this was bit self-contradictory (see
changes in odfexport.cxx and check_cross_references.py tests)
