Link to Plurals of class names #10

As requested, I'm opening an issue based upon this ruby forum thread:

http://www.ruby-forum.com/topic/931304#976952

This is kinda going to be a slippery slope I'm afraid. I guess you could do a simple "remove the trailing s" and look. But a general way to link to the Class's page would be nice too so that I can do "list of children[class_link:Child]" (perhaps) and RDoc would fill in the proper link to the page for Child.

Good luck!
