New binary tool (aka. fix makews.js)

[martinheidegger]

@khalifenizar kindly provided makews.js a long time ago that creates a stub of a workshopper.
It would be good to update this and create a proper workshopper-adventure binary.

npm i workshopper-adventure -g
workshopper-adventure new learnyoufancyframework

should

1. check if learnyoufancyframework is taken in npm (and abort if it is)
2. create a new folder learnyoufancyframework
3. create a package.json that has a dependency workshopper-adventure with the namelearnyoufancyframework the version 1.0.0
4. create a index.js file that references and specify it as main in the package.json
5. create an executable bin/learnyoufancyframework file that references index and add it as bin to the package.json
6. add a dev-dependency to workshopper-adventure-test and add the test to the scripts.test of the package.json
7. add node_modules to .gitignore
8. Add readme.md with stubs.
9. run git init

(optionally)

1. use the github api to create a learnyoufancyframework project under the current user.
2. use the github api to add information (email, name, repository) to the package.json
3. add git remote and push to origin

Discussion If this is added to workshopper-adventure then then this will make workshopper-adventure heavier. Maybe its better to put it into wa-gen or alike npm package.
