Final steps in CrudRestController refactoring for RESTful API autogeneration
Optional dictification of objects in JSON responses
Improve errors detection in PUT and GET
Enable submitting values with a JSON body and refactor test suite
add support for If-Unmodified-Since conditional PUT requests
First try for robust get_all

json requests simply get a 400, html requests will get a flash warning
and their query will be discarded.
Probably the URL could/should be rewritten, too.
