Improvements to challenge mode

[byorgey]

Some left over ideas from #285 :

• Provide a mechanism for a sequence of challenges, e.g. a tutorial where after doing one challenge you can progress to the next. Perhaps put a bunch of challenges in a list in a single file, and provide a way for the user to signal when they are ready to progress to the next challenge.
  • Split out into "Meta-scenarios" consisting of sequences of text + other scenarios #355 .
• Perhaps some improvements to the way challenge descriptions/goals are shown, winning is flagged, etc.
  • Split out as Improvements to challenge scenario UI #356.
• Possibly generalize challenges to just descriptions of how to initialize a game --- so classic and creative modes can be "just" generated by descriptions of how to initialize the game rather than special built-in modes.
  • Done in Generalize challenges + classic/creative modes to scenarios #337 .
• Write up some documentation on how to author a challenge
  • Split out as Documentation for how to author scenarios #354 .

We could further split out some of these into their own issues, but I just wanted to make sure they got preserved.

Also related to documentation 🙂

• Fix README to mention challenges:

  (TBD) In Challenge mode, where you attempt to program robots in order to solve pre-designed puzzles or challenges.

And a bit more futuristic:

• Integrate with Menu screen #4 (this would be awesome 🤩 )
  • Done in Generalize challenges + classic/creative modes to scenarios #337 .
• Save challenge status (Not started/In progress/Finished) in XDG_WHATEVER_DIR (for browsing in the menu)
  • Split out as Save scenario completion status #357 .

On the idea of

Provide a mechanism for a sequence of challenges, e.g. a tutorial where after doing one
challenge you can progress to the next,

in each challenge file, you could have a next value which references another challenge file to be done next (if the player so chooses).

You could also have a 'meta challenge' which is just a list of challenge file paths. This way, the challenge sequences collections don't even have to be linear!

Note: this was originally @byorgey 's idea.

Closing this issue since all the mentioned ideas have now been split out into their own separate issues.
