Js-ipfs: Support exposing API/Gateway on multiple multiaddrs

[lidel]

go-ipfs supports listening on multiple multiaddrs if an array is provided instead of a single multiaddr.

Both snippets are valid in go-ipfs:

ipv4+ipv6

    "Addresses": {
        "API": [
            "/ip4/127.0.0.1/tcp/5002",
            "/ip6/::1/tcp/5002"
        ],
        "Gateway": [
            "/ip4/127.0.0.1/tcp/9090",
            "/ip6/::1/tcp/9090"
        ],

ipv4 only

    "Addresses": {
        "API": "/ip4/127.0.0.1/tcp/5002",
        "Gateway": "/ip4/127.0.0.1/tcp/9090",

Unfortunately js-ipfs does not support arrays, only a single address can be defined ATM.
