    currency-provider: Don't ever download rates if refresh interval is 0
    
    If an admin has set the currency refresh interval to 0 they probably
    don't ever want the data refreshed from the network.
    
    This commit treats a refresh interval of 0 specially to mean
    "don't go on the network at all"
