    Make `isValidIP()` backwards compatible with deprecated `is_valid_ip()`.
    
    The old `bridgedb.Bridges.is_valid_ip()` function expected a single
    string parameter, and would return a boolean. The new
    `bridgedb.parse.addr.isValidIP()` function expected an
    `ipaddr.IPAddress` as a parameter.
    
     * CHANGE `bridgedb.parse.addr.isValidIP()` to convert any strings which
       it receives as arguments into `ipaddr.IPAddress`s, which makes it
       backwards compatible with the (deprecated)
       `bridgedb.Bridges.is_valid_ip()` function.
