* rulesets/Entity.cpp, rulesets/Entity.h, rulesets/LocatedEntity.cpp,
rulesets/LocatedEntity.h: Remove raw atlas attributes, and use
properties for everything, cutting down the differences in
interface.
* rulesets/Py_Thing.cpp, rulesets/Thing.cpp: Remove code that accessed
soft attributes directly.

server/WorldRouter.h: Refactor all the entity code so there is now
a new base class for entities in the world simulation, and in the
mind which only contains things which are trully common to both.
This moves a lot of functionality which should not have been
present in mind entities away, and makes that code safer and more
efficient.
* tests/TestWorld.h: Update the test world API to match the base
class.
* rulesets/Entity.h: Make the attribute interface virtual.
* rulesets/LocatedEntity.cpp: Add in basic implementatios without
properties of the attribute interface.
