Calling "is_valid" checks whether the goal actually can be fulfilled.
If it can't be, False is returned.
By default all Goals return True unless a "validity" function is supplied
in the constructor.
For now we only use it for checking whether movement goals can be reached.
Instead of treating a goal error as something which will make the entity
inactive, we instead allow for some errors (namely three currently) to
occur before the goal is deactivated. Any other goals are however
allowed to carry on even though one goal is faulty.
We also expose this through the goal_info query functionality, allowing
for world authors to better debug faulty goals.
* rulesets/basic/mind/panlingua/interlinguish.py: Add the list verb.
* rulesets/basic/mind/Goal.py: Add a __repr__() method to make it
more intuitive to get a text representation of a goal.
* rulesets/basic/mind/NPCMind.py: Add a handler for the list verb
that causes all the matching knowledge to be listed.
* configure.ac: Increment version.
* common/const.h: Declare a doxygen group for all the consts.
* common/operations.cpp, common/Add.h, common/Attack.h, common/Burn.h,
common/Chop.h, common/Connect.h, common/Cut.h, common/Delve.h,

common/Mow.h, common/Nourish.h, common/Pickup.h, common/Setup.h,
common/Tick.h, common/Unseen.h, common/Update.h:
Declare a doxygen group for all custom operations.
* rulesets/Area.h, rulesets/Character.h, rulesets/Creator.h,
rulesets/Entity.h, rulesets/Food.h, rulesets/Line.h,
rulesets/Missile.h, rulesets/Plant.h, rulesets/Stackable.h,
rulesets/Structure.h, rulesets/World.h: Declare a doxygen group
for in game entity classses.
* common/Property.h, common/Property_impl.h, server/ScriptFactory.cpp,
server/ScriptFactory.h, server/SlaveClientConnection.cpp,
server/SlaveClientConnection.h: Add some more inlined documentation.
* modules/Location.cpp, modules/Location.h, rulesets/Python_API.cpp:
Implement a function for determining the horizontal distance
between two locations neglecting height difference, as for
locations on the terrain it is not relevant.
* rulesets/basic/mind/goals/common/move.py: Improve the coding of
the move_me_to_it goal, so distance determination is more effective.
Make distance independant of height.
Relax distances at which character is concidered to have arrived at
its destination.
* rulesets/basic/mind/Goal.py: Modify goal so that it understands
that a subgoal can be unfulfilled, but still not need to take any
action.
server/Account.cpp, rulesets/Entity.h, rulesets/Entity.cpp,
rulesets/Character.h, rulesets/Character.cpp, rulesets/BaseMind.h,
rulesets/BaseMind.cpp, common/types.h, common/operations.h,
common/op_switch.h, common/BaseEntity.h, common/BaseEntity.cpp:
Added support for imaginary operations used in a similar way
to emoting.
* server/WorldTime.h: Added update method so underlying DataTime
can be updated.
* server/ServerRouting.h, server/Lobby.h, server/Lobby.cpp
server/ServerRouting.cpp, server/Connection.h,
server/Connection.cpp, server/Account.h, server/Account.cpp: Added
a lobby object which handles lobby chat. Essentially it stores
a list of accounts and allows operations to be sent or broadcast
to other accounts.
* rulesets/Py_WorldTime.cpp: Added python is_now() method because
using comparison does not appear to work.
* rulesets/BaseMind.cpp: Added updating of minds WorldTime each
time an operation is received.
* modules/DateTime.h: Added operator << so DateTime can be sent
to cout.
* common/types.h: Added types for storing accounts in Lobby.
