tnrs_db: pause: Increased to 30 min because if no new names are available in TNRS.tnrs, there is no need to check every minute for new names (which clutters up the log file output). The pause feature is designed to allow tnrs_db to run in parallel with the import process, and process new names as they are made available, which only happens once for each partition of each datasource.

tnrs_db: Fixed bug where the new filtering out of already-scrubbed names caused names to be skipped, because the loop would both advance by the number of rows found and those rows would no longer be returned by the query, causing only every other set of rows to be processed

tnrs.py: tnrs_request(): Rewrapped lines (became >80 chars after adding profiling)

tnrs.py: tnrs_request(): Use new encode() and TnrsOutputStream to escape TNRS-invalid characters

tnrs.py: Added encode(), decode(), decode_for_tsv(), and TnrsOutputStream to handle escaping TNRS-invalid characters

strings.py: Added regexp_repl_esc()

strings.py: Added replace_all() and replace_all_re(), as well as flip_map() for use with maps for these functions

csvs.py: Added tsv_encode_map for use in creating TSVs parsed by TsvReader

csvs.py: TsvReader: Also interpret '\t' as a tab, to provide a mechanism for encoding embedded tabs

tnrs.py: gwt_encode(): Escape special characters in the string instead of removing them, so that TNRS receives the original name rather than a modified version. This will help make the submitted names match up with the returned Name_submitted.
