Make group info more informative.
Fixed bug & simplified code by displaying list of menu choices vertically as far as screen space allows, first,
and in columns 2nd, instead of in columns 1st.  Might fill the screen more often but that's worth the simplicity.
Was running into bug: "Unable to show remaining <N> items in the available screen space...".
bugfixes around display of no more entities when going back to top of list, and screen space.

Refactor: use new method askYesNoQuestion in many more places to simplify.
