Link Rally Ho Thread

[Ramblurr]

All the other repos have links to their canonical bay12 thread:

Rally Ho needs one: http://www.bay12forums.com/smf/index.php?topic=149172.0

Also [16x16] should be added

Good thought about adding a link. I don't know how to edit that top line, but I just added a readme file with a link. I don't think I can change the names of this stuff.
