Links Out in the www

I just realized that there wasn't a "Links" link on Stencil Archive's main mast head. I guess that this got forgotten after last year's upgrades. I do not have time to dig too deep to figure out a better way to check the links on here.

For now, links of the main link categories:

ARTISTS: http://www.stencilarchive.org/links-artists

COLLECTIONS: http://www.stencilarchive.org/links-collections

SERVICES: http://www.stencilarchive.org/links-services

RESEARCH: http://www.stencilarchive.org/liks-research

Now... to figure out how to get Drupal to check for broken links!
