A couple of small WCM updates...

[Wain]

A couple of small additions to Warcraft Mounts.

• At the bottom of the individual mount pages, you should see a list of other mounts that use the same model (usually different colours)
• Also at the bottom, you may see "matching companion pets" for some mounts. The list is mostly fairly conservative, and limited to ones that match very closely. There are a few stretches, but it's hard to know where to draw the line. We're open to more additions in the future, though
