Merge pull request #289 from keithj/devel

Added a path transformation for the new fastnfs filesystem
Fixes a bug introduced in 1.5.13 where an ArrayRef is passed to a
method that expects an Array. For consistency, the method has been
converted to accept an ArrayRef.
Fixed the Sequenom SNP call query to fetch the latest results for the
specified plex, not simply the latest results. Removed post-query
filtering by plex.
