HV-905 Providing a global config for auto unwrapping

An early attempt. Any thoughts on the direction?
For the sake of testing, I changed this into the following:

    Property<@MinTypeUse(value = 3) Number> integerProperty = new SimpleIntegerProperty( 2 );

That way the constraint is not validated, though. I think the reason is that in `ValidatorImpl#validate()` the check `if ( !beanMetaDataManager.isConstrained( object.getClass() ) )` yields that the class is not constrained and we thus instantly return. Apparently type annotation constraints don't contribute to the "isConstrained" state of property metadata et al.
