Description

This commit fixes many problems:

tolerances of the translations, determining if a symmetry is symmorphic or non were inconsistent
the non-symmorphic symmetries were not used for symmetrizing ionic positions
the non-symmorphic symmetries were not used for symmetrizing forces
the total forces was not symmetrized according to the space-group

Moreover, the commit also adds:

a printing of the spacegroup at each GO step if debug=info
a improved printing of symmorphic and non-symmorphic symmetries at the begining of the output

With these changes, the space group should be always conserved during a GO run, if symmetries are used.

News snippet

Multiple improvements and fixes for geometry optimization in solids when symmetries are employed.
