[#26] object: Rename UserHeader to Attribute

Browse source 
The name of object.UserHeader message implies its use by the user. However,
the attributes of an object can also be set internally by the system. To
generalize the intended purpose of the message, this commit renames it to an
Attribute (like container.Attribute).
