tnrs.py: max_pause: Changed to 30 min because TNRS sometimes freezes for ~10 min. The freezing usually happens while the data is being uploaded rather than when it's being retrieved, so that the max_pause would not apply, but to be on the safe side, requests should not time out unnecessarily.

tnrs_db: tnrs_profiler: Use iter_text='name' for consistency with tnrs.tnrs_request()'s own profiler's iter_text

tnrs_db: Print cumulative profiling information after every TNRS request, rather than just at the end

inputs/.TNRS/tnrs/tnrs.make: Append to the log file instead of overwriting it, so that the TNRS scrubbing of each import's new taxonomic names can be included in one log file. Echo the command to the log file to identify separate runs.

TNRS-related programs: Use "names" instead of "taxons" for variable names because what's being submitted are actually verbatim taxonomic names, not official references to specific taxa

tnrs.py: tnrs_request(): Profile the TNRS request

tnrs.py: tnrs_request(): Fixed bug where initial_headers needed to be copied instead of just assigned to headers, because initial_headers is a global constant and should not be changed when the Cookie header is added

mappings/VegCore.csv: originalTaxonRank, acceptedTaxonRank: Fixed sources to use verbatimTaxonRank, not taxonRank

mappings/VegCore.csv: originalTaxonRank: Added source of the original* prefix

mappings/VegCore.csv: acceptedTaxonRank: Added source of the accepted prefix
