o rdkit gains a RDKit::common_properties namespace that contains common string value properties
o Dict.h and below gain getPropIfPresent that attempts to retrieve a property and returns
true/false on success or failure. This is used to optimize access.
o rdkit learns how to pass property keys by reference, not value.
A new namespace has been added to RDKit, common_properties
that contains the std::string values for commonly used
properties. This helps to avoid typos in string values
but also avoids a creation of std::strings from character
values. All accessors (has/get/clear and getPropIfPresent) now pass
the key by reference.
Additionally, getPropIfPresent removes the double lookup
of hasProp/getProp which can be a significant speedup
in the smiles and smarts parsers (10-20%)

In order to fix the problem, the value of the query function for atomMass queries
is being multiplied by a constant factor (currently 1000) before converting
to an int. This allows distinguishing between things like [CH4] (where the
C has mass 12.011) and [12CH4] (where the C has mass 12.000).
a couple of little hacks to cleanup the smiles produced from a substructure query (not guaranteed to be correct, but better);
additional internal consistency checks;
stop throwing an exception from inside the smarts parser... that just screws up later parses (this should be fixed!);
better cleanup from failed parsing;
