Some twitter fixes

I have some fixes for the twitter support. 1st change makes it tolerant of entering your twittername with space at the beginning or end:

-$username = $twittername; // Your twitter username.
+$username = trim($twittername); // Your twitter username.
 if ($username == ""){
 	$username = "wordpress";
 	}

2nd change makes the server automatically create the twitter cache file if it doesn’t exist, and alerts you if the file can’t be written by the server:

         @fwrite($cache_static,$content);
         @fclose($cache_static);
     }

Both of these changes are in functions.php … if you can’t figure out the diff format, just change the line that is marked “-” at the beginning to the version that is marked “+”.
