add basic structure for additional features documentation

Setting the raw frame with overview, short descriptions like in code
and already revealing skill levels.

Based on the current (recently modified) structure of the feature settings.

Detailed descriptions in work and coming with later commits as well as
a dedicated admin section for that topic. Better menu integration
may be possible with Andrew's new doco structure work in progress later.
