I would like to categorize entities by custom tags, e.g.:

  • In Greenhouse #1155, I would like to distinguish between entities that are "flowers" vs. "mushrooms"
  • In fishing scenario #1628, I would like to distinguish between entities that are either "junk" or "useful", with perhaps subcategories of "edible" and "inedible".
  • It may be useful to group together multiple entities as different "states" of the same thing, such as an "empty cask" and "water-filled cask", such as in beekeeping scenario #1599.

The implementation should be straightforward; just add a new field in the YAML description of an entity that accepts a list of strings (the "tags").
A new command hasTag : text -> text -> cmd bool that answers whether an entity has a given tag. This would be primarily intended for system robot use, though there is probably opportunity for creative uses as a scenario mechanic for players.

Implement entity tags and commands (#1635)
37cae2a 
Closes #1631

## Design

* Entities have a new property: a `Set` of textual tags.
* Two new commands are introduced:
    * `HasTag` checks whether a single entity has a given tag
    * `TagMembers` allows cycling through all members with a given tag
* `TagMembers` may be considered more powerful than `HasTag`, so has its own separate capability (`CTagmembers`).
* A map is computed at scenario initialization to facilitate `TagMembers` lookups.
* Tag names are highlighted in yellow in markdown.

## Demo

    scripts/play.sh -i scenarios/Testing/1631-tags.yaml --autoplay

## Other changes

* Incidentally, changed `knownEntities` from a list to a `Set` so that `Set.member` can be used instead of `elem`.
