OpenWFE 1.3.0 released

OpenWFE 1.3.0 includes control.sh (and control.bat) tools for [un]freezing expressions and cancelling flows. These tools are command-line only for the moment.
The introduction of this control system implies that now the engine also has its passwd.xml file, access to the control system is restricted to users having a valid ControlPermission.
The choice of encoding between components is now made by the dispatcher, the listener adapts to it. This has induced a small change in the socket dispatching protocol, that's why it became 1.3.0 instead of 1.2.3.

- [engine] task #101355 : wrote control.bat and
etc-engine/win-engine-policy.conf
- [engine] task #100658 : implemented ControlSession (command line only
for the moment).
- [engine] task #101575 : re-implemented retry for SocketDispatcher.
Freeze only occurs after the retries failed.
- [engine] task #101467 : dispatcher now advertises its encoder name,
so that listener may adapt.
- [engine] task #101466 : implemented coder advertisement in socket
dispatching, SocketListener now adapts to encoder chosen
by dispatcher.
- [engine] refactored FlowExpressionId and FlowExpression cloning.
- [core] bug #981839 : creating a new user failed. Fixed.
