Minor fixes to database scripts


Corrected filename typo and added proper handling of training directory in
convertPrIMe

Allowed for any number of reactants and products in convertPrIMe and
queryNIST
Fixed reference typo in training script
Modified queryNIST script to handle upper- and lower- limit rates
Added C-Compiled scripts to .gitignore
Removing RMG-Java database entries
Removed unicode characters from reference titles
Added script to split PrIMe repositories into NIST and PrIMe counterparts

All entries are first checked for the existence of CAS identifiers for
each species.

Entries with at least one unidentified species are likely to fail on NIST
query, so they are kept in the PrIMe database and will be manually updated

Entries with no unidentified species are consolidated to unique reactions,
then cross-referenced against NIST. Kinetic data (including T and P ranges)
and references are updated appropriately, with the squib entry used as the
entry label.
Modified PrIMe-splitting script to accept 'Book' reference type

(instead of just 'Book Chapter')
Modified PrIMe-splitting script to ignore relative reaction rates
Modified PrIMe-splitting script to ignore results without valid T-ranges
Minor code cleanup
Fixed relative rate handling
Handling for blank category and datatype
Tweaked cookie handling order
Added tracking for lost identified reactions
Modified script to ignore results without a valid order
Removed faulty PrIMe-splitting script
Added new PrIMe-splitting script
Fixed page-grabbing from squib
Slight restructuring of splitPrIMe script, added CAS output
