csvs.py: sniff(): Also autodetect the line ending

inputs/test_taxonomic_names/Taxon/+header.txt: Changed line endings to \r\n to match testNames.txt line endings. This will be necessary when the line ending is autodetected by csvs.sniff().

csvs.py: TsvReader.next(): Renamed raw_contents var to line, since this is just the line with the ending removed

strings.py: Replaced no longer used contains_any() with find_any(), which returns any found substring, or None if none of the substrings were found

csvs.py: Modify csv.Dialect._validate() to ignore "delimiter must be a 1-character string" errors, in order to support multi-char delimiters used by TsvReader

csvs.py: Modify csv.Dialect._validate() to ignore "delimiter must be a 1-character string" errors, in order to support multi-char delimiters used by TsvReader

csvs.py: TsvReader: Use str.split() instead of csv.reader().next() to parse the row, for efficiency and to support multi-char delimiters. This is possible because the TSV dialect doesn't use CSV parsing features other than the delimiter and newline-escaping (which is handled separately).
