Multiple directories + skip already optimized

[seansan]

Great script thanks! Two small things ...

**1 Can we add more than 1 directory to scan? (a list)

**2 Suppose we run this file more often, say every week or day: can the script sort-of 'skip' the files that were scanned yesterday for example? (no need of inspection again) and only do the new files? For example is there a date option to only include files that were changes between now and 7 days ago?

thanks, Sean
