Removed old soft-clipping filter

    - A new soft-clipping filter was added a while
      ago where a read is not 'perfect' if more than
      10% of the read is soft-clipped.

    - The old soft-clip filter kept track of the end
      coordinate of a soft-clip at the beginning of a
      read and the start coordinate of a soft-clip at
      the end of a read.  For all reads that were soft-
      clipped at the beginning, the reads that had the
      most common soft-clip end coordinate were no
      longer considered 'perfect'.  For all reads that
      were soft-clipped at the end, the reads that had
      the most common start coordinate were no longer
      considered 'perfect'.  Basically, all reads that
      soft-clipped at the same coordinate (either at
      the beginning or the end) were no longer
      considered 'perfect'.
