PR from seven that I will now update in aurora

@sneridagh So I've been working alot on the automatic changing of the sidebar when specific options are selected.

Before when I understand it correctly you were only able to change one sidebar option per click. I changed that so you can add "sideEffects" to your schema that will get changed too.

I tried to just use the value to set everything but the value only changes the looks of the sidebar not the actual component.
Now my question would be is this something that we want to change the way i did that? Since we don't use the adapter in aurora I think this approach makes sense. With every new Block we add we can set these sideEffects very easy and the logic in the schema is only limited to the onChangeSideEffects.
