* Deprecation: planned removal of .message() and .getMessage() methods
* Deprecation: planned removal of old MolHash code
* document deprecations
* output the diffs when the psql tests fail
* remove .message() from SWIG wrappers
note that the KeyError doesn't work properly. We should clean up the the exceptions here anyway
* typo

clang-format the results
clean up all the parts that clang-tidy-8 broke

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%)
