Option to supply socket.io instead of using global io

[maritz]

This is especially relevant if you need seperate socket.io connections for garageserver.io and something else.

Also, relying on globals is never good. ;)

(I can make this myself this weekend and send a pull request, if you want)

Makes sense.

I'm assuming that you're referring to the GarageServer.IO client?

[maritz]

Yes, the socket.io usage in the client. :-)

A pull request would be great!
