Auto-advance on submitting a response in forms

[abhsarma]

Is your feature request related to a problem? Please describe.
Responses created in the config.json such as buttons should have the option to auto-advance the participant to the next trial. This is necessary for perceptual studies such as the correlation task or the stroop test which require participants quickest response.

Another related option could be to prevent participants from changing their response after they've selected an answer. But this could be potentially unnecessary

Describe the solution you'd like
For the auto-advance feature, two additional fields under response:

{
  ...
  "autoAdvanceToNextStep": true, // 'false' by default, could be set to 'true'
  "autoAdvanceDelay": 300"
}

For disable:

{
  ...
  "allowResponseChange": true, // 'true' by default, could be set to 'false'
}

Should every response technically be able to do that? For numerical and text fields it might make sense as well with the autoAdvanceDelay.

Should this ignore required fields and go to the next step regardless if there is any missing information or not?

And how would allowResponseChange work with checkboxes or multidroprown? With radio buttons and text I can think of a solution (radio when clicked disable selection and for text/input when focus is lost).

I don't think this should be supported for all response fields. I guess only buttons, radio and likert (which is essentially a special case of radio). I think with the others, response end might be more tricky to figure out.

Outcome of the discussion with Abhraneel: Implement autoAdvanceToNextStep, autoAdvanceDelay, allowResponseChange, just for buttons and do not ignore the required fields and show a warning if a study is created and more than 1 question is present (more than 1 response is possible) and autoadavance is set to true
