Using double borders for acceptance states in SBAs.

Browse source 
* src/tgbaalgos/dotty.hh (dotty_reachable): Take a new
assume_sba argument.
* src/tgbaalgos/dotty.cc (dotty_bfs): Take a new
mark_accepting_states arguments.
(dotty_bfs::process_state): Check if a state is accepting using
the state_is_accepting() method for tgba_sba_proxies, or by
looking at the first outgoing transition of the state.  Pass
the result to the dectorator.
(dotty_reachable): Adjust function.
* src/tgbaalgos/dottydec.hh, src/tgbaalgos/dottydec.cc,
src/tgbaalgos/rundotdec.hh, src/tgbaalgos/rundotdec.cc
(state_decl): Add an "accepting" argument, and use it to
decorate accepting states with a double border.
* src/tgbatest/ltl2tgba.cc: Keep track of whether the output
is an SBA or not, so that we can tell it to dotty().
* wrap/python/ajax/spot.in: Likewise.
* wrap/python/cgi-bin/ltl2tgba.in: Likewise.
