encoding to utf-8 and then fixed related fields

see on wiki, details for each file. Most were ANSI csv and UTF-8 txt
(ocr output). Changing encoding of CSV, then fix verbatim lat / lon,
coordinates, often verbatimscientificname too.
csv encoding to utf-8, fixed related fields

all csv files in this set, changed encoding to utf-8. then fixed errors
as noted on wiki usually including verbatimScientificName,
verbatimCoordinates, verbatimLatitude, VerbatimLongitude, sometimes
habitat, sometimes fieldnotes. the words "latitude" and "longitude" were
removed from the verbatimcoordinates field as they represent labels, not
values.
