Support dashes in the resource list in qsub.pl

[MaigoAkisame]

I am using the script contribs/torque/qsub.pl to submit a job to a specific node:
qsub -l nodes=foo-bar foo.sh
However, the node name, which contains a dash, is not recognized by the qsub script.

The problem lies in Line 244:
($opt{$key}) = $rl =~ m/$key=([\w:+=+]+)/;
The character class (enclosed in brackets) in the regexp doesn't include the dash.

Since node names with dashes are not uncommon, I would appreciate it if you could add - to the character class in the regexp.
