Socket.io connector

[J0B10]

Description

The Tipeeestream connector and the StreamElements connector already use socketIO but it may be beneficial to have a simple connector to listen for or emit socket events directly.

We could also use some inheritance to save a some duplicated code.

The same applicable to the REST connector #85, as i could be a supertype for OLA #142 or AHK #140.
