Hey, what's the status on this, @vdayanand?

With WebSockets.jl master, HTTP.jl master, Mux with JuliaWeb/Mux.jl#66 , WebIO with JuliaGizmos/WebIO.jl#169 and Blink with this PR, I get all of the WebIO tests and Blink tests passing on Julia v0.7. I think we're in good shape if we can get everything merged and tagged.

Getting all this worked out would be super helpful to me, as I rely on Blink.jl for ECharts.jl.
