quiz.js - improve the code

[rguliev]

For now, a template of the code in quiz.js (the part that is related to questions) is not that good. I would suggest using new Question approach (see example).

• [ ] In quiz.js create a function function Question(type=1) {...}. The output is an object of the following structure:

  {
  "type": 1, // Question type. By default is 1, i.e. from en/ru to Arabic
  "choices": [choise0, choise1, choise2, choise3],
  "correctChoise": 0-3,
  "text": "What is Arabic for 'She said'?"
  }

• [ ] In bot.js use new Question()
