State Machine Framework: make UnconditionalTransition public

Hi,

please make UnconditionalTransition publically usable.

Reference

Perhaps QUnconditionalTransition, or something.

Why?
I think this may be interesting, since one can then do:

// c++11

QUnconditionalTransition *trans = new QUnconditionalTransition{state};

QObject::connect(checkbox, 
                 &QCheckBox::toggled, 
                 [](bool leaveImmediate) { trans->setTargetState(leaveImmediate ? state : nullptr); } 
                );

This is an easy way, to conditionally specify

• to leave a state immediately on entering
• or not (if TargetState is nullptr).
