As Ive had the coaster slot-labelling code running in worker.pl for quite a while, Im committing it into trunk now. Its been very costly for me to keep re-integrating it as worker.pl evolves.  If better ideas on how to do this come up, we can revise or remove it.

This code sets SWIFT_JOB_SLOT and SWOFT_WORKER_PID in the environment of executed app() jobs.

I'll also commit a change to coasters build.xml to copy worker.pl to bin/ and mark it executable.
