Echo JS 0.11.0

This first part basically consists in setting up a development environment on Windows. Not a single line of JavaScript...

Also, I find the choice of Scoop as a package installer quite unusual, when alternatives like Chocolatey and NuGet are much more en vogue. But well, I guess avoiding a monoculture is good.

On the other hand, ConEmu is nice although I would have used Cmder (which is a wrapper for ConEmu).

What I'd *never* do is writing "jQuery" in all caps.
