Add filename based timings.

Duration, start day/time, end day/time implemented.

Duration allows for a specific file to run for a specific duration.
Start day/time allows a specific file to run at specified day/time.
End day/time moves a specific file to an archive folder, which stops it from running.

Example:
	filename[_dur][_start][_end].ext
