Added a use_multistep input variable that allows fourier modes to be gradually included.
Added a langevin opt_scheme in which the string performs a langevin dynamics in the path space.
In the langevin scheme a canonical sampling of the initial and final configurations can also be done "on the fly" setting first_last_opt=.TRUE..

are grouped into modules starting with "path_". The output has been slightly
restyled. In the pwscf code (only) has been implemented a version of the string
method (calculation='smd') in which the path is represented in Fourier components
and the optimization procedure is done on these components (still to be
optimized, but working).
