Notes

• This PR is growing big. So I decided to put some features into the next PR, which includes support for all built-in types of answers and multi-response in one trial.
• I added a second participant selector on trial panel on the left side. Now we support randomized sequence and latin-square sequence, so trials and sequences may be different for each participant. We may need to discuss how to integrate individual playback here.
