Resource name/route aliases

[pond]

Extend the resource interface DSL to support resource name aliases.

This is useful for cases where, as time goes by, it becomes obvious that a particular resource is part of a growing family with a particular naming strategy but one historically named item is inconsistent, making things less easy to follow/understand in documentation and just generally more ugly. To avoid breaking historic callers the resource should forever be addressable by its original name(s), while also renaming it to a new recommended form.
