#11 Add a "Redirect" message to the WM-Client protocol

[Robert Moore]

This item is an idea still being worked out. It will not be implemented in the immediate future.

Extend the World Model-Client protocol to include a new "Redirect" message which will indicate that a URI has changed values, but that the referenced information is the same. The message should contain the following fields:
Current URI - the current (FROM) URI value
New URI - the new (DESTINATION) URI value

Effects:
The previous URI value should have all Attributes expired, a new Attribute "copied-to" will be created with the "New URI" value.
The new URI value should be created and all current Attribute values copied over from the current URI. An additional Attribute "copied-from" will be created with the "Current URI" value.
