[evolution-data-server] Camel: Add CAMEL_STORE_CAN_EDIT_FOLDERS flag.

    Camel: Add CAMEL_STORE_CAN_EDIT_FOLDERS flag.
    
    Basically for the NNTP provider to clear, or I suppose if you're
    proxying someone else's account.  Evolution can check for this flag
    and disable folder create/delete/rename actions in the context of a
    newsgroup server.
    
    Related to bug 656720.
