Document the PATCH mapping generated by resources and single

[codeconsole]

The guide documents seven mappings for resources and six for single. Both generate one more — PATCH has been generated since the action was added and was never documented, including in the "Explicit REST Mappings" equivalence list.

"/books"(resources: 'book')

is equivalent to eight mappings, not seven:

get    "/books"(controller: "book", action: "index")
get    "/books/create"(controller: "book", action: "create")
post   "/books"(controller: "book", action: "save")
get    "/books/$id"(controller: "book", action: "show")
get    "/books/$id/edit"(controller: "book", action: "edit")
put    "/books/$id"(controller: "book", action: "update")
patch  "/books/$id"(controller: "book", action: "patch")   // undocumented
delete "/books/$id"(controller: "book", action: "delete")

Adds the missing row to the resources, single and nested-resources tables in the URL mappings guide, and to the two action-convention tables in the REST section.

Also corrects the nested-resources table, which gave the edit URI as /books/${bookId}/authors/edit/${id}. The generated mapping appends /edit after the id, as asserted by RestfulResourceMappingSpec.
