Several changes. The generated list of specific decompositions with a specific bathymetry is saved using the checksum of the file to avoid recalculating if repeating the experiment. Additionally some bugfixes.

Conflicts:
	src/Makefiles/Makefile.mn4

Not necessary to select model to link bathymetries, by default both nemo and ece bathymetries are linked

Adding the option to use EC-Earth grids instead of the NEMO standalone ones. Script linking the bathymetries modified.
