No change when using option "unsorted" as sort order with picard_sortsam

The purpose of this option "unsorted" is unclear. From what I can tell, the dataset is unchanged. Could we clarify what the purpose of the option is in the tool form? Is it a needed option but not functional yet?

Also, samtools_sort does the same operations (without the "unsorted" option) and succeeds with both coordinate and read name options. Users will probably install both picard and samtools as complete packages. Do we need both of these tools? Or should one be retained to avoid user confusion?
