Generalize question concept

[SilasBerger]

Currently, a question simply loops until it receives the correct answer, then continues with the next beat.
In a more general concept, a question could simply be a function, which maps a given input to

• any of x possible next dialog branches ("Would you like a tougher challenge?" -> yes-path / no-path)
  • Since game definitions are pure TS files, each path can be stored in a variable, which should make merging easy
• a response + loopback (as we currently do on wrong answer)
• any side effect (backend request, capturing an artefact (see below), etc.)
• any combination of the above
