extended path: adding support for calibrated shock.
...
This commit is not satisfactory because it uses M_.det_shocks
for unexpected shocks. We need to improve on it soon.

Fixed ep.init option.
...
Initialization of the perfect foresight solver (in extended path) with
the solution of the first order approximation of the model was broken.
If the value of options_.ep.init is "true"" (1) then the solution of the
first order approximation is used as an initial guess for the newton
lilke solver. If the value of options_.ep.init is "false" (0) the solver
is initialized with the steady state.

Allow (S)EP with arbitrary sequence of innovations.
...
The third input argument of extended_path Matlab/Octave's routine is the
sequence of shocks (T*n array, where n is the number of exogenous
variables and T is the size of the sample). If the third argument is
empty, the (stochastic) extended path is run with gaussian
innovations (this corresponds to the previous behaviour).
TODO:
- Fix the compatibility with ep.replic_nbr
- Check the 'calibrated' mode.

Transposed the definition of the innovations in (stochastic) extended path routine, so that, for a given state of the random number generator, stochastic simulations obtained with extended_path and stoch_simul commands consider the same innovations (when the number of shocks is greater than one). Otherwise the stochastic simulations cannot be compared.
