Instead of directly setting position and orientation we've now
added a "transforms" property. This property contains zero or many
transformations. The result of these is what drives changes to an
entity's position and orientation.
By cleanly separate disrete transformations we can more easily undo
or alter them. This allows us to do things where the position or
orientation of an entity is affected by other properties, or other
entities.
The client protocol is intact. Changes to position and orientation is
still sent the same way, by specifying "pos" and "orientation". However,
these values will now not be written directly to corresponding values on
the entity. Instead they will first be written to the "transforms" property,
with the final values being a result of combining all data in the property.
Since some properties are class properties without any state we need to
add a "remove" method to call, rather than putting cleanup logic in the
destructor.
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/LocatedEntity.cpp, rulesets/LocatedEntity.h: Make all the
property access functions that should never be used to modify a
property const. Remove requirePropertyClass() as it pretty much
can't be const.
* rulesets/Entity.cpp, rulesets/Entity.h: Make overriden
getProperty() const as it is in the base class. Add new
property access functions for code that needs to modify the
properties which ensures class properties never get modified
through the Entity interface.
* rulesets/Character.cpp, rulesets/Plant.cpp, rulesets/Py_Thing.cpp,
rulesets/TerrainModProperty.cpp, server/CorePropertyManager.cpp:
Change all the code that accesses properties to use the right

called when the attributes of an Entity are changed.
* rulesets/Entity.cpp, rulesets/Entity.h, rulesets/LocatedEntity.cpp,
rulesets/Thing.cpp, server/WorldRouter.cpp: Implement onUpdated()
to emit the updated signal on Entity, and change all code to
call onUpdated instead of emiting the signal.

server/SlaveClientConnection.h: Factor out the more pointless base
classes, in favor of simple interface. Move destroyed signal to
Entity, which is the only place it is needed.
* rulesets/LocatedEntity.cpp, rulesets/LocatedEntity.h: Add a virtual
function that is called when the location of an entity changes.
* rulesets/Entity.cpp, rulesets/Entity.h: Implement the virtual
function called when location changes and use it to call the
containered signal. Remove the containered_oneshots list, and
make containered inherently one shot only.
* rulesets/OutfitProperty.cpp: Remove the use of containered_oneshots
is this mechanism is obsolete and has been removed.
* rulesets/LocatedEntity.cpp, rulesets/LocatedEntity.h:
Don't allocated storage for m_contains by default, only
on demand. Add a convenience method which checks, and
allocates the storage if required. Set up the ID property
on this base class rather then Entity.
* rulesets/Py_Thing.cpp: Remove special handling of ID attribute
as it is now handled by the property.

the right checks, as it could be null.

anything don't waste the storage.
* rulesets/Entity.cpp, rulesets/Entity.h, rulesets/LocatedEntity.cpp,

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.
