Would the usage always be like this? (Re res[0])

    ipfs.id(function (err, res) {
       if (err) throw err
       if (err) throw err
      var id = res[0]

In that case, I would suggest doing that before returning, so people wouldn't have to duplicate the grabbing of the first element of res in every single api call.

Also, we should probably have some tests at least to ensure src/request-api.js is working as expected.

@victorbjelkholm that is only temporary, the res[0] is very annoying atm but wanted to get sth up to see if it works as expected.

Re tests for request-api itself, I think when we have the tests from #81 we should be fine

@victorbjelkholm fixed
