Review 21909

C. Thomas Tyler
Added 'JobIncrement' trigger script to simplify use of custom Perforce
job names (i.e. not following the default jobNNNNNN convention) when
not integrated with an external defect/issue tracker.

This will be used by The Workshop, but seems reasonable to include in
the SDP as some customers might find it helpful.
