cgi: Add an nondeterministic monitor option

* src/tgbaalgos/postproc.hh (run): Rename the first argument as
input_disown to help Swig.
* wrap/python/spot.i: Wrap spot::postprocessor.
* wrap/python/ajax/ltl2tgba.html, wrap/python/ajax/protocol.txt:
Add an option for nondeterministic monitor.
* wrap/python/ajax/spot.in: Honor the new option, and rewrite the
monitor production using postprocessor.
