another try at Julia v0.7 support

[rdeits]

Combines #145 and #157

Fixes #172
Fixes #164
Fixes #128
Fixes #47

[rdeits]

All the WebIO tests except the blink-tests.jl file pass on v0.7 with this branch, but none of our communication actually works because the websocket support via Mux/WebSockets is still not working.

[rdeits]

Good news! With JuliaWeb/Mux.jl#66 , HTTP.jl master, WebSockets.jl master, and the latest changes from b09b03c we now have working websockets in WebIO on v0.7! The clock demo and "random print button" demo from the readme are both working for me with Mux on v0.7.

[rdeits]

Blink integration also seems to work with JuliaGizmos/Blink.jl#139

[rdeits]

More changes may be required in the future, but I think we should go ahead and merge this so we can focus on getting Blink working via JuliaGizmos/Blink.jl#139 and vdayanand/Blink.jl#3

[rdeits]

Ok, I'm going for it :)

Won't build for me still:

Looks like it is the load error for dir()

@lewisl you need the master branch of WebIO.jl. pkg> add WebIO#master should do it

[lewisl]

I never explicitly requested any particular branch. If I didn’t get master it is because something is wrong with the build process for the package.

@lewisl This version was not released yet. So you got the old released version.

…

[lewisl]

Thanks. Master was older branch; thought it was released. Master built and compiled.
