During the time of the initial release of Peer Calls, the server and
client sockets used to have different namespaces - one side had `/#`
prepended to the name, whereas the other did not, so I had to check for
this in the code.
This was fixed since the release of [SocketIO v1.5.0][1], thus breaking the
compatibility with PeerCalls. Any new `npm install` would break this
because of the way it works - it tries to install the latest available
"compatible" release.
As of this commit, the SocketIO version is locked to v1.6.0.
