FSE-only classes

From old feedback: FSE-only classes | Cwicly

Option to add classes to blocks which only gets applied inside the builder, not on the frontend.

This is very needed when working with the interactions add/remove/toggle class options.

There are more (crucial) reasons to add this feature, so I hope this will be a thing soon.

Option to toggle applied (enable/disable) classes, maybe just by clicking on the classname.
Useful for global classes and additional classes.

I think this option would replace my initial feature suggestion as a more powerful implementation.
