InkBox 2.0

Biggest release of InkBox OS ever. Yes, the time gap between 1.9 and 2.0 is huge, but we hope you will find that it was worth it.
Thanks to @Szybet for greatly contributing to the project, now for over one year and counting, as well as every other direct or indirect contributor.
We are always seeking for engaged contributors : maintaining this project with only two people can be very hard, frustrating and mentally taxing at times.
We cannot guarantee that development will continue if it becomes too much for us.
