Serve documents when a module keeps a collection, not by its inputs' names

pure-serve took a module with an input named show or edit for a
document app and refused it unless both were keyed messages: an app with
a plain message named edit compiled and then would not start (review
004, an earlier P2). Documents are what a module keeps in a keyed
collection; now the host serves them when the module declares one, and
inputs named show and edit are otherwise messages as any other.
check.py's server_plain_edit starts such an app and posts to edit.
