Check and add missing stuff from the battlecard doc

Closed Achilleas Pipinellis requested to merge features/battlecards-check into master

We're deprecating the battlecard doc in favor of features.yml.

  • Marked as DONE are features that are included in features.yml.
  • Marked as missing are features that are not included at all and are tracked in
  • Those with a question mark (?) in front of them, I didn't know if they should be included at all.

This MR adds any missing information for existing features. Also closes
