Bump engine.io

[marcelaraujo]

Please, bump Engine.io package up to 1.5.3.

The version 1.5.2 breaks on Node 4.0.0.

See #2245 for a temporary fix for Node 4

@torvalamo Thanks

[radum]

This doesn't solve anything if socket.io is a dependency.

[torvalamo]

No, for that to be fixed they have to push it npm. Not sure why they haven't.

@rauchg Can we get an update to npm with the node 4.0.0 fix?

[maxscott]

+1 here too... sufficient for direct dependency on socket.io, but not if through another project (or multiple). Would love to see an npm update.

[davispuh]

npm install socket.io fails to install with Node 4.0 because specified bufferutil doesn't compile for it.
