fixing an issue that can come from this missing data during a upgrade from old cobalt versions.

Closes #11

See merge request !2

adding new command to produce a PBS qsub from a cobalt qsub

See merge request !1

per Paul's suggestion I added the shebang line to the --directives output so it now produces output that can be redirected to a file and used as a script input to PBS.  I also added a # before the two note lines so they are commands and don't cause errors in the script

changed resource name from host (already defined) to system, added the missing = in the select (how the hell did that disappear?) and also caught another error.  Need to add the -- when directly running an executable, which required another command line option

Addressed comments from code review and found a further corner

get added to clusters.  Tests added and behavior fixed for those.
