Web form:

- Improvement about web form manipulation (remove a field, set a text value to input fields by name, ...)
 - Improved web form html generation, especially for select and type checkbox
 - Updated the date input field interface with a new set_date_value .

File response:
 - "application/force-download" is not a standard MIME content type, so use "application_octet_stream" instead as default.

Standalone connector:
 - Added expected creation procedure for the service launcher.
 - Added new "secure_port" configuration variable, for SSL standalone service.
   This way, if `is_secure` is True, the server will use `secure_port` (overrides `port` value).

Date:
 - Improved support for RFC 3339 (a profile of ISO 8601)

Removed obsolete and warnings:
 - removed usage of FILE_NAME
 - updated code to avoid implicit conversion from STRING_32 to STRING_8
 - avoid uneed conversion to STRING_8 (when possible)
