Policy Plus - Attribution for icons

I noticed while putting together some materials for the upcoming Tech Fair that the FamFamFam "Silk" icons that everyone uses everywhere are under the Creative Commons Attribution 2.5 license, which means there should be a note and a link to the author's site accompanying uses of them. To comply with licensing and generally be a good Internet citizen, I added an attribution document to the Policy Plus repository with the appropriate information. I also linked to the Microsoft documents that were very helpful in writing the ADMX/ADML/CMTX loaders.
