Zaahir/fix duckpan help

/cc @yegg @nospampleasemam 

The most important part of this is where I've commented out the test for a Version number in the `duckpan help` output. With the changes made by @djinn this is no longer in the output, however it does appear in the man page, so I opted not to force it in the POD because it will create a duplicate in the man page.
