* 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.
