Change icon to remove a widget and improve alert when removing a widget

[sim6]

Please, could you improve the alert when you click the red cross on widget banner, saying that this widget is removing for everybody?

Moreover, I think the cross should be changed by a trash icon.

These changes were done in web version.

Thanks!

Thanks, but I cannot see it in Version 0.8.21 (F-610fc121d).

It will be visible in 0.8.22. Please be patient :)
