Add a text popup when hoving over the Canvas item tag

A lot of the canvas items’ descriptions end with “that can display images from the internet” which seems a bit redundant. Also there’s less room for funny jokes in the descriptions : (

I think it’d make more a bit more sense to include this text as a popup that appears when hovering over the Canvas item tag, like the Wearable and Equippable tags have, since that way that information would be there by every canvas item without needing to repeat it in the description each time.
