Title: Use \x00 as the default quote char when parsing CSVs/TSVs.

By default, the quote char that the CSV parser uses (to quote fields) is "
http://ruby-doc.org/stdlib-1.9.2/libdoc/csv/rdoc/CSV.html#method-c-new

This causes a lot of parsing errors, though, since people often upload files with legitimate quotation marks. (It's quite rare, at least in my experience, to actually have quoted fields in a CSV/TSV.)

AFAICT, there's no way to tell the parser that columns are never quoted, so per the SO suggestion [here](http://stackoverflow.com/questions/8073920/importing-csv-ruby-1-9-2-quoting-error-driving-me-nuts), I'm using a zero-byte char (which should never occur) as my quote char.
