Not compatible with Jekyll 3.0

[devjack]

It looks like 'something' is using a deprecated method read_posts.

Specifically:

Configuration file: _config.yml
jekyll 3.0.0 | Error:  undefined method `read_posts' for class `Jekyll::Site'
Warning:  Use --force to continue.

Full CLI trace:

Yep, we should update Jekyll to the new version and appropriate configurations. Maybe someone want to make a PR? Because I am currently working on Project Hoverboard
