Add ability for tracker to say what the current sprites are

[LiminalityCarb]

It would be nice (especially when using random sprites) to have tracker be able to provide the details of the sprite(s) that are being used. She is able to pull that information when providing hints (such as referring to the Link sprite when the item is in Hyrule) but it could be helpful to be able to ask tracker to say what the sprite is.

Sorry, just realized while going through things of HOW to do this via just the tracker YAML files. Will see about adding a fork later with it there.

- Phrases:
  - what is the current link sprite
  Response:
  - Text: The current link sprite is {{Link}}
  - Text: That sprite is {{Link}}
- Phrases:
  - what is the current samus sprite
  Response:
  - Text: The current samus sprite is {{Link}}
  - Text: That sprite is {{Samus}}

Yeah, that'll do it. I think we might want to add a special command for it, though, to at least include the sprite author, too. And a ship sprite command; I don't think we have a placeholder for that.

Possibly an MSU command too, if we don't already have that. Less important since we have the MSU window, but still.

There are voice commands for the MSU and track info.
