Adds custom feedback tool that reports to github issues.

Adds a custom feedback tool to  skeleton that pushed to github issues directly 

It works by handling the click event (and stores the clicked point in the report). It also generates a url that is accessible with the clicked point shown.

I have a node.js server running on Heroku that is connecting with the Github Api with my account. (For this reason, the repo has to be public or within ginetta organization).
