Decide any other supporting files/data which ought to be captured when database is re-constructed from primary data

[davidlmobley]

There are other supporting files/information aside from those we currently provide which have been requested:

• Include frcmod files created in parameterization
• Include ZINC compound IDs via https://github.com/rasbt/smilite
• Better flagging of cases which might have problematic tautomers, perhaps using a mechanism like that suggested by OpenEye here: https://www.evernote.com/l/ABpN_7k6J4hPG4Ye4o06M7RKtc_ad4YKHJE

See also #14, concerning content of SDF files.

Closing this (via #28) but I'll make a separate issue so we can do something to flag tautomers with potential issues.
