Script content reactive to form

[geoffreyweal]

Currently, if the user makes a change in the script content and then makes a change in the form, all the changes that the user made to the script content will be reset.

This update does two things:

1. The script content is reactive to the form. That is, if you make a change to the script content, it will be updated in the form.
2. By doing this, the user does not need to reset their script content if they reset the form.

Thank you for the PR. I am currently away on a business trip, so it may take some time for me to make a decision.

No problem.

For a bit of context, this edit is based on user experience who wanted to be able to modify the script and change form options afterwards.

Thanks
