A couple of small atomType fixes for Fluorine, that were causing segfaults when testing the database ReactionMechanismGenerator/RMG-database#317

Otherwise when trying to make a sample molecule
with an F groupAtom, it fails (and crashes
with a segfault)

Thanks!
Please see a couple of comments

While at it, and although beyond the scope of the PR title, perhaps add I as well?
BTW, if Ar is here, should we also consider He and Ne?

Good point with I. Added in subsequent commit.
He and Ne are already listed.

atomTypes['F' ] = AtomType('F', generic=['R','R!H','Val7'], specific=['F1s'])
atomTypes['F1s'] = AtomType('F1s', generic=['R','R!H','F','Val7'], specific=[],
single=[0,1], allDouble=[0], rDouble=[], oDouble=[], sDouble=[], triple=[0], benzene=[0], lonePairs=[3], charge=[0])
single=[0,1], allDouble=[0], rDouble=[], oDouble=[], sDouble=[], triple=[0], quadruple=[0], benzene=[0], lonePairs=[3], charge=[0])

The default value for quadruple is an empty list. Shouldn't that be enough (I guess not from your experience with F, but I wonder why)?
Perhaps a quicker fix for all elements would be to change the default behaviour of AtomType.
I suggest editing line 118 to:
self.quadruple = quadruple or [0]
so zero quadruple bonds becomes the default.

Actually, we don't know that the default was causing a problem, we just thought we'd make Fluorine the same as Chlorine. I think our actual problem was solved by the other change.

This list should cover all elements used in atomTypes.
