batch process for SwarmGui

Additional changes to all versions of signal_Plotter_44( ), in order to
give as output the "h" struct, with all GUI parameters, functions and
buttons.
In signal_Plotter_44( ) the savealltracks function was modified to be
able to receive the destination folder as an input argument. Not used in
the GUI, but useful when there is the need to call the function from
outside scripts.
