Phame - allow blogs to specify custom URIs

Summary: this then enables people to create blog.theircompany.com. And for us, blog.phacility.com...!

Test Plan:
 - created custom URIs of various goodness and verified the error messages were sensical.
 - verified if "false" in configuration then custom uri stuff disappears
