Activate add parent/children on All/Any options

This adds a third option on a parent node, and makes the code much easier to work with.
Adding a new node, is done by updating the JSON structure, and letting react re-render.

Chose a pretty basic glyph - just to distinguish between function. Temporary, needs UX.

TODO:
- Removing children not functional (yet) ... well, kinda works when you remove a tree of them. More work needed. 
- Consolidate all the is/included/not/percentage operand react components into one. (this is easier to do with this concept)
