[patch] bitrate rounding errors on short mp3s

I have a bug and a patch, and I'm not sure if I'm supposed to send 
things here or bugs.kde.org :)


Given a very short mp3 (or any other mpeg file, really), with a 
Xing/Info header, the bitrate calculation has a rounding error.  On line 
221, the length is forced into an integer; for a short sample with a 
non-integral length this leads to the bitrate being incorrectly 
calculated.  (My testcase had 13.7 seconds of audio in a 64kbps CBR mp3, 
and it was rounded to about 67.)
