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.
* data/basic.xml, data/characters.xml, data/mason.xml: Add tick
properties to a bunch of entity classes so they no longer need
a setup operation to get them going.
* rulesets/mason/world/objects/Weather.py,
rulesets/mason/world/objects/elements/Fire.py,
rulesets/mason/world/objects/plants/seeds/Apple.py: Remove setup
handlers from a bunch of scripts as it is now handled by
properties.
* data/buildings.xml: Add setup property to entity classes which
really need a setup op at startup.
* client/BaseClient.cpp: Send a look when creating the avatar, so
that notifications get back without the need for a special case.
* common/op_switch.h, rulesets/Creator.cpp, rulesets/Entity.cpp,
rulesets/Entity.h, server/WorldRouter.cpp:
Remove the setup operation sent to all entities on startup by
default. Get rid of some special cases that depended on it.
* rulesets/InternalProperties.cpp, rulesets/InternalProperties.h:
Make the tick property schedule the operation on apply(), and
use the property value as the time to schedule it.
* rulesets/InternalProperties.cpp, rulesets/InternalProperties.h,
server/CorePropertyManager.cpp: Add a pair of new property classes,
one to schedule an immediate setup operation, and one to schedule
an immediate tick operation.
