Various Job utilities

This toolkit has become somewhat truncated as most functions may now be
found included in the OS or in widely used toolkits.

        SUSJB [job_id,] timeout%

Suspends a job for timeout% frames, where timeout% = 0..32k or -1 (=>
forever). The job ID may be omitted => myself, or set to -1 => myself,
or be the ID of some other job. A more advanced version of this command is
now incorporated into SMSQ/E (V3.34+), but not in Qdos/Minerva.
