I was asked why, while setting the seed, the shocks were not the same in a
simulation based on 1st order or on 3rd order.

It took me a while to realize that condest() that is used in
dyn_first_order_solver.m is calling rand()

I think that we need to change the way we control the random generator. I
suggest that set_dynare_seed only set the value of options_.dynare_seed and
that before each function where users can expect to control a random sequence
we use options_.dynare_seed to reseed the random generator. We could use
keyword 'time' for dynare_seed so that we reseed with system time

I am fine with both the idea of reseeding at relevant places, and to add
the possibility of seeding with time.
