Adding changelog entry.

adding comments about this change

Removed the bool from ProcessAnimationMessageQueue as it was no longer needed.

replacing the bool... (doh) ><
Needed that to mark the message processed.

Still work in progress.  This revision adds the ability to synchronize late joining clients with more than one trigger that might have been triggered recently.  This only will be synchronized if the layer's current state hash is the same as the trigger's current or next state hash.

comments.

This is a new approach to synchronizing transitions with late joining players without having to actually set the associated conditional trigger.  By building a small list of all states and then building a quick lookup table, we can just synchronize the "transition state" which for late joining clients is a cross fade between the start and destination state.  We synchronize the normalized time (where it was in the transition on the server side when the client connected) of the transition this way as well.
Now, we just synchronize states (which some can be transition states).

Updated a property name and added some network log warning and error messages.

increased number of client
Fixed issue where the late joining client was not being shutdown at the end of the LateJoinSynchronizationTest.

Since the next update will be a minor revision, removed the "if defs" and just using ISerializationCallbackReceiver.

- Removing the packing since we gain nothing unless we are packing unsigned long values.
- Caching the NetworkManager to assure we have one when cleaning up on the server side.
- Added an error message and removed TODO comment.
