omit the square root calculations, so that when their values

* rulesets/BaseMind.cpp: Added updating of minds WorldTime each
time an operation is received.
* modules/DateTime.h: Added operator << so DateTime can be sent

Al Riddoch <alriddoch@zepler.org>
* Substantial re-work of object model. Moved many attributes out
of BaseEntity class. Changed WoldRouter so it now handles
objects in terms of Entity, rather than BaseEntity.
* Code cleanups, including removing reduntant includes, and
getting rid of C style comments.
* Fixed the way attributes are handled in Set operations and
when merging from an Atlas::Message::Object. This fixed
problem with setting gender of characters.
* rulesets/Pedestrian.*, rulesets/Movement.*: Re-named
Movement variables to make them clearer. Added in
separate handling for collisions from moving to
target position. Modified collision handling so
objects can slide next to each other.
* rulesets/Thing.cpp, rulesets/Character.cpp: Cleaned up and
rationalised movement code. Much shorter, faster and
more compact than before.
* Made better use of iterators throughout, eliminating unnecessary
lookups, and copying of data.

less work for the linker.
* Made more use of const references to avoid the need to copy
data before being able to inspect it.

begin with a lower case letter and do not contain _.
* Fixed retrieval of Account from database so that the Account
is now correctly referenced in the server object.
* common/types.h: Changed type name to make them clearer.
* rulesets/Character.h: Moved MovementInfo into its own class
file, and made it a base class, with a Pedestrian super class.

to be used to handle things that move differently.

script types to be cleanly dropped in.
* Re-work on server and communication related classes to use
references where they are apropriate. Code is now much more
robust.
* Huge cleanup of header files removing redundant includes.
* server/WorldRouter.h: Removed is_object_deleted because it
is broken and not used.
* server/Connection.h: Removed unused disconnect() methods.
* rulesets/Entity.*: Added new in game base class from which
all mind and object classes are derived. This removes
clutter of Thing class from mind classes.
* aiclient/*: Progress with creating AI client for mind handling.
* common/globals.*: Moved some globals out of server specific files.
* rulesets/Makefile.am: Separated rulesets code into 3 almost stand
alone packages; entities, mind and python interface code.
Acorn may well not work now, but I would apreciate it if people could
test the code on their setups. Lots of code has changed, and almost
everything is now cleaner.

into individual files for each bit.
* aiclient/*: Added client mode cyphesis for handling AI in another
server. Not yet operational.
* */*: Moved large and virtual functions out of headers to reduce
multiple instance problems, keep the binary size down, and speed
up compilation.
* server/Admin.h/cpp: Added Get operation handling, thus dividing
admin commands into two classes, one which does not alter
the state of the server, the other which does. Added query
command which allows admin client to retrive arbitrary objects
from server id dictionary.
