As long as the OEAssumption::BondedResidue flag is
turned off, OEGetResidueAtoms now correctly returns
an iterator for every atom in a residue when some atoms in the
residue are not connected to others.
Because some crystal symmetry space-groups share the same
space-group number which can lead to the use of the wrong space
group operators, when possible the name of the symmetry is now used
rather than the space group number.
