Last.fm normaliser - algorithm change

After much head-scratching and a few hairy moments with the database this afternoon, we have updated the Last.fm Normaliser to use median track length values in its calculations, rather than the arithmetic mean values used previously.

Hopefully, this should smooth out a lot of the issues people were reporting with a handful of extra-long or extra-short tracks skewing the figures for a particular artist or album.
