Add hints

[ollelauribostrom]

As proposed by @wenzelmkay in #67, we could add some kind of hint functionality to the game. This could work something like this:

1. The user enters an incorrect answer n (maybe two/three) times
2. If the rebus has a hint property, display the hint below the input fields

For example, if the rebus data looks like:

  {
    symbols: ['Re', '+', '🚌'],
    words: ['Rebus'],
    hint: 'You´re solving one right now'
  },

The text You´re solving one right now would be displayed after the user has entered an incorrect answer n times.

Is this issue still open? May I contribute to it? Which file would I have to contribute to in order to work on this?

@andyn95 This already is being worked on in #168 🙂
