S3 Gateway running error

[BlueNokia]

As instructed in https://github.com/storj/storj/wiki/S3-Gateway test-network setup was successful.
But when trying to run it by ~/go/bin/gateway run --address :7776 it gives

Error: unknown flag: --address

Then going for gateway run
it shows

Uplink configuration error: failed to connect to overlay: transport error: connection error: desc = "transport: error while dialing: dial tcp 127.0.0.1:7778: connect: connection refused"

@BlueNokia The flag is now called server.address
You can always find the help using gateway run --help

As referenced in the other issue #1418 You need to run the testnetwork while trying to access it via the gateway.
I will update the S3-Gateway document to reflect the new config flag.
