Cannot create new guided tour through the interface

[Crejak]

Context

The UDV web client only provide an interface to consult and navigate through guided tours. The contributors have no way of creating / updating / deleting a guided tour, even though the services exist in the back-end API.

Solution

A new interface must be created to allow users to contribute to guided tours. It might be an extension (similar to "Contribute" which was an extension to "ConsultDoc"), or just a new part of the existing module (like "DocToValidate" which allows to consult, udpate, delete, comment in one module)
