Can GET the plaintext output of a job.

This needs to be coded differently, because foreseeably there
could be multiple output files and this returns the data of the

Perhaps /srcproc/:instance/jobs/:id/prop/:prop is better.
Merge branch 'frontend_merge' into vince_devel
Taking their index.html

handle asm/jcl use cases.
Began using JCLProcessor module; broke things.
Added JCLProcessor to the script includes.
added error case where JES rejects the job.
Output inserts into new tab. Textobject bugs.

work for all cases.

Added functionality for saving to file.
Added button to old version.
Handles case where job takes too long to complete. Added util funcs.
