Added xClip Clarification

Added a small Find Your VM Number Guide

Added a small guide to find your vm number.

closes #18
Sidebar Links!

Added sidebar extending functionality. A markdown file that
defines a `sidebar: {'link name': 'link target'}` variable in the
header will have a sidebar generated for it.

This will help aid navigation of long tutorials, and make linking
other users to specific sections easier.
