feat: import items from another board

[Meierschlumpf]

Describe the feature you'd like to request

Add the possiblity to add items from another board to the current board.

Describe the solution you'd like to see

The way is not yet defined and has to be discussed in this issue.

Additional information

We currently have this import item button that does nothing. The question now is how we should allow the import from another board.

@SeDemal on discord:

Import from config, list all configs available to that user (maybe restrict to the ones the user has power of modification on too)
import from file, after clicking the config make a list of the widgets with selects?
If you select all then that imports the whole config

With config you mean board right? But how can the user differentiate between the same kind of widget on one board?

[SeDemal]

I do mean board yes. Got mixed up.
I hadn't thought of the possibility of having more than one of the same widget x)
Maybe by having a preview of the look of the widget and it's options (in a submodal on a preview button or accordion like details)?
