newline symbol correction for fields value before send to server

[cgi-caesar]

I believe last line of function $.fieldValue should looks like:

return $(el).val().replace( /\r?\n/g, "\r\n" );

Otherwise standard submit and ajax submit will result with different newline symbol on server script on linux machine.

Please refer how jQuery serialize form.

Best Regards.

It makes sense to match jQuery core's serialization logic.
