Description

Adds:

• '--loop N' - causes the program to loop forever, sleeping for up to N seconds between loops (loop time minus collection time, unless that's less than 0, at which point it will just run again immediately)
• '--asjson' - display as a JSON string instead of the more human readable output format.

Neither of the above depend on each other (you can loop in the human readable output, or do a single shot execution with JSON output). Existing behavior/output maintained if neither of the above are used. Diff Attached.
