Plugin Support for UTF-8

Hey There,
Just used this great plugin and it works great.

just one thing, in the Excel export he don’t work well with Latin Characters.

so i fixed it.

i fix it in file: lib/cf7_adb.class.php
Line: 77

			//header("Content-Disposition: attachment; filename=\"$filename\"");
			//header("Content-Type: application/vnd.ms-excel;");

            //headers
            header('Pragma: public');
            header('Expires: 0');
            header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
            header('Content-Description: File Transfer');
            header('Content-Type: text/csv');
            header("Content-Disposition: attachment; filename=\"$filename\"");
            header('Content-Transfer-Encoding: binary');

//open file pointer to standard output
            $fp = fopen('php://output', 'w');

//add BOM to fix UTF-8 in Excel
            fputs($fp, $bom =( chr(0xEF) . chr(0xBB) . chr(0xBF) ));

            fclose($fp);

Hope it works well.
Good luck!
