Commented the demo/server in a new module.

Embedded its PICS in the server documentation (hopefully a good idea).
Added a PrettyPrintPropertyValue() function to the epics program (hopefully OK format).
Added a function apdu_service_supported_to_index() to the apdu code to translate a SERVICE_SUPPORTED_ enum to its SERVICE_CONFIRMED_ or SERVICE_UNCONFIRMED_ index, and used it when PrettyPrinting services.
