[Telepathy] Icon Naming spec: rename user-idle to user-extended-away

[Guillaume Desmottes]

Hi again,

Is there any reason to have named user-idle that way? 
The icon used when a user on a chat network has not been an active
participant in any chats on the network, for an extended period of time.

Reading its description user-extended-away sounds like a more sensible
name and would fit better with current terminology used in IM clients.
