All IG code should use the interface of LocatedEntity when dealing
with any entity, rather than sometimes requiring Entity. Add virtual
functions to the interface where required, and modify all other interfaces
to stop them using Entity. This makes the code way cleaner, and much better
de-coupled.
* rulesets/ArithmeticFactory.h, rulesets/ArithmeticFactory.cpp:
Fix up ArithmeticFactory code to be in rulesets, and allow
for the case where there is no owner for the script.
* rulesets/Character.cpp, rulesets/Character.h: Remove all traces
of the hard coded statistics property from Character.
* rulesets/Py_Property.cpp: Don't use Py_StatisticsProperty as the
default wrapper for a statistics property because it will no
longer work this way.
* rulesets/Python_API.cpp: Remove the setup for the Statistics
wrapper.
* rulesets/StatisticsProperty.cpp, rulesets/StatisticsProperty.h:
Change the footprint of this class so it is no longer hooked
into part of the Character class, and instead handles looking
up values from the script directly, and owns the script itself.
* server/ArithmeticFactory.cpp, server/ArithmeticFactory.h,
server/EntityFactory.cpp, server/EntityFactory.h,
server/PersistantThingFactory.cpp: Remove setup of hard coded
statistics property.
* rulesets/Statistics.h, rulesets/Statistics.cpp,
rulesets/Py_Statistics.h, rulesets/Py_Statistics.cpp,
rulesets/Makefile.am: Remove clases that are no longer used.
