This enables CORGI.
Currently, AphrontSite subclasses can't really have their own routes. They can do this sort of hacky rewriting of paths, but that's a mess and not desirable in the long run.
Instead, let subclasses build their own routing maps. This will let CORP and ORG have their own routing maps.
I was able to get rid of the PhameBlogResourcesSite since it can really just share the standard resources site.
