Title: Code/GraphMol/AddHs patch proposal

- modified Code/GraphMol/AddHs.cpp so that hydrogens are not
removed when the heavy atom they are connected to is not
in its default valence state, while it has one of the
acceptable valence states (otherwise it still has to be
removed for sanitization purposes)
- updated the MMFF validation suite SMILES accordingly
