dot: add an option to output id= attributes

Browse source 
This will be handy latter to develop widgets with interactive
highlighting of automata.

* spot/twaalgos/dot.cc: Implement it.
* bin/common_aoutput.cc, NEWS, doc/org/oaut.org,
doc/org/spot.css: Document it.
* tests/core/alternating.test, tests/core/readsave.test,
tests/core/sccdot.test: Test it.

Each state, edge, or SCC in an automaton has a unique number. When
passing option =i= to the dot printer, this unique number will be used
to form a unique =id= attribute for these elements: a prefix =S= (for
state), =E= (for edge), or "SCC=" is simply added to the unique
number. Additionally, using =i(graphid)= will define =graphid= as
that =id= of the automaton. GraphViz will keep these identifier in
the generated SVG, so this makes it possible to modify rendering
of the automaton using CSS or javascript.
As an example, the CSS file we use on this page contains:
#+BEGIN_SRC css
#iddemo #E3 path{animation:flashstroke 1s linear infinite;}
@keyframes flashstroke{50%{stroke:red;stroke-width:1.5;}}
#iddemo #E3 polygon{animation:flashfill 1s linear infinite;}
@keyframes flashfill{50%{stroke:red;stroke-width:1.5;fill:red}}
#+END_SRC
therefore the third edge of any graph whose =id= is =iddemo= will
be animated:
#+NAME: oaut-dot4
#+BEGIN_SRC sh :exports code
ltl2tgba -G -D 'GFa <-> XGb' --dot='i(iddemo).'
#+END_SRC
#+BEGIN_SRC dot :file oaut-dot4.svg :var txt=oaut-dot4 :exports results
$txt
#+END_SRC
#+RESULTS:
[[file:oaut-dot4.svg]]
