[@svelteui/core]: actionicon add onclick event

[uvulpos]

Description

I want to be able to make an action, when an action button is clicked. I could wrap a div around, but I think thats a very silly workaround and a responsibility of the component. Therefore I also had to adapt the Box Component to bubble up the onclick event
