dotty: get rid of the decorated version

* src/tgbaalgos/dottydec.cc, src/tgbaalgos/dottydec.hh,
src/tgbaalgos/rundotdec.cc, src/tgbaalgos/rundotdec.hh: Delete.
* src/tgbaalgos/Makefile.am, wrap/python/spot.i: Adjust.
* src/tgbaalgos/dotty.cc, src/tgbaalgos/dotty.hh: Remove the
decorated version, and the related arguments.
* src/bin/common_aoutput.cc, src/bin/dstar2tgba.cc,
src/tgbatest/ltl2tgba.cc, src/tgbatest/complementation.cc,
src/tgbatest/emptchk.cc: Adjust calls.
* wrap/python/ajax/spot.in: Draw the accepting run as an
automaton instead of painting it.
* wrap/python/ajax/ltl2tgba.html: Update help text.
