Artwork DB auto-approval

[Alex Cabal]

Mike Colagrosso has just merged an update to the artwork DB. When
submitting a new artwork, if it's from an approved museum then the
system will now check the artwork page for the appropriate license
information. If found then the artwork will be auto-approved, so you
won't have to wait for another editor to review it.

Thanks Mike!

It's a great system (and getting better!) and fantastic resource. Kudos to Mike!
