Add github template functionnality to this repo

[honeyspoon]

There is new repository template functionality offered by Github that allow users to click a button to generate a repo based on the template.

I think this is good because a link to the original template is added to generated repos and this allow forks to be used for real project forking to add new functionality or make contributions.
Also adds a /generate endpoint if you want to programmatically generate a repo in a tutorial.

Here are steps to make this repository a template.

I can't think of a reason not to add this.
