Modify the powerset algorithm to keep track of accepting states

Browse source 
from the initial automaton.

* src/tgba/tgbaexplicit.cc, src/tgba/tgbaexplicit.hh:
Added class tgba_explicit_number, a tgba_explicit where states are
labelled by integers.
* src/tgbaalgos/powerset.hh, src/tgbaalgos/powerset.cc:
When building the deterministic automaton, keep track of which states
were created from an accepting state in the initial automaton.
The states are added to the new optional parameter (if not 0),
acc_list.
Use tgba_explicit_number instead of tgba_explicit_string to build
the result.
* src/tgbaalgos/scc.cc (spot): Small fix.
Print everything on std::cout.
