* rulesets/mason/world/statistics/Statistics.py: Make this a new style class so properties work right, and implement it all as properties. * rulesets/StatisticsProperty.cpp: Move the setup of the script instance into apply rather than install, otherwise it doesn't get called in the right place. * rulesets/ArithmeticScript.h: Add a set method to the interface. * rulesets/PythonArithmeticScript.cpp, rulesets/PythonArithmeticScript.h: Implement getting using PyObject_GenericGetAttr() as it works. Add a completely new set function. * rulesets/Entity.cpp: When a new property is installed it needs to be applied.
