Add the simulation in the Spot web interface.

* wrap/python/ajax/spot.in: Add the simulation.
* wrap/python/ajax/protocol.txt: Add the direct simulation in the
automaton simplifications section.
* wrap/python/spot.i (simulation_new): Create a function which
takes an automaton and a call to the simulation with the good
template parameter.
* wrap/python/ajax/ltl2tgba.html: Add the direct simulation
checkbox.
