Supports a new global configuration property: SERVER_SECURED.

This property can take two values: either true or false. True means Silverpeas
is running after a secured reverse proxy (id est a reverse proxy ensuring TLS
connections).
The secure attribute of the session tracking cookie is valued with this
property when constructing the silverpeas application.
