Lots more photo references!

I've spent part of the weekend digging through Otto Perry's photos, online at the Denver Public Library, and updating links.

The link additions to my Rolling Stock page alone resulted in many more photos of RGS locomotives #20, #25, #40, #41 and #42.  There were numerous additions to the route listing pages as well, including a couple of bridges I had no photo links for previously (18-A, 68-A).
