Add summary only support

[steven10172]

Currently YARM supports displaying as warning, full table, and hidden. When you enable the summary, you'll only see the relevant summary based on that mode. I typically play with full table in early game and swap to warning. Later in the game it would be useful to have another option that always displays the summary of all planets, as well as current planet only, without enabling full table.

I also have been wanting this, as well as "current surface only" as an extra filter.
