* lib/csv/csv.rb: Reworked CSV's parser and generator to be m17n. Data

is now parsed in the Encoding it is in without need for translation.
* lib/csv/csv.rb:  Improved inspect() messages for better IRb support.
* lib/csv/csv.rb:  Fixed header writing bug reported by Dov Murik.
* lib/csv/csv.rb:  Use custom separators in parsing header Strings as
  suggested by Shmulik Regev.
* lib/csv/csv.rb:  Added a :write_headers option for outputting headers.
* lib/csv/csv.rb:  Handle open() calls in binary mode whenever we can to
  workaround a Windows issue where line-ending translation can cause an
  off-by-one error in seeking back to a non-zero starting position after
  auto-discovery for :row_sep as suggested by Robert Battle.
* lib/csv/csv.rb:  Improved the parser to fail faster when fed some forms
  of invalid CSV that can be detected without reading ahead.
* lib/csv/csv.rb:  Added a :field_size_limit option to control CSV's
  lookahead and prevent the parser from biting off more data than
  it can chew.
* lib/csv/csv.rb:  Added readers for CSV attributes:  col_sep(), row_sep(),
  quote_char(), field_size_limit(), converters(), unconverted_fields?(),
  headers(), return_headers?(), write_headers?(), header_converters(),
  skip_blanks?(), and force_quotes?().
* lib/csv/csv.rb:  Cleaned up code syntax to be more inline with
  Ruby 1.9 than 1.8.
