Where should Custom Mansions folder go?

[RobSeegel]

I actually wish I could define a spot using preferences that is outside of the distro. I'd prefer it to be easily accessible under my home directory and not directly attached to the distro. Ultimately, it wouldn't matter that much though, since I can create links to the folder regardless of where it ends up. The reason that I favor this approach is that it would let me decide where it was most convenient.

Also, I like the idea of the custom mansions existing outside of any one distro so I don't have to move things around if I upgrade or test different versions, etc.

It could default to #1.
