Automatically save/autosave the user's work in the form editor after every change

I think that automatically saving the user's work in the form editor after every change they make would be a better workflow than clicking the save button to save their work.

I notice that in practice, most users click the save button after every change they make.

Not autosaving also allows for the possibility of accidentally losing work by closing the project before saving.

If we implement autosaving, we should also implement a versioning system where you can "save as" to create a version of the project and then continue working, then switch to the other version as needed. This will require some UX and technical thinking to develop.

@prestoncabe mentioned that this might require grouping the entire screener project into one object, which sounds like a good idea to me.
