* rulesets/TransientProperty.h, rulesets/MultiHandlerProperty.h,
rulesets/MultiHandlerProperty.cpp, rulesets/MindProperty.h,
rulesets/InternalProperties.h, rulesets/HandlerProperty.h,
rulesets/HandlerProperty.cpp: Switch a bunch of pretty simple
property classes over to using Propery<> rather than
DynamicProperty<>.
* rulesets/HandlerProperty.h, rulesets/HandlerProperty_impl.h,
rulesets/HandlerProperty.cpp: New property class which uses the
install method it insert an operation handler function
instead of using a messy active property factory as we have done
so far.
