Rename CGI.escape_html to CGI.escape_xhtml

Avoids overriding Ruby's built-in CGI.escape_html. Also fixes two bugs
in the original: :defualt typo and 'node' instead of 'mode' in error.

   # * `:quote`     - escapes single and double quotes
   # * `:newlines`  - escapes newline characters (\r and \n)
   # * `:ampersand` - escapes the ampersand sign
