QoL Suggestions: Item Tradability Tags

[Anonymouse#3759]

Note: I wasn't sure if I should post this suggestion in the rewards section or not.
I feel an easier way to know if an item is tradeable would be in its tags on the site's personal inventory page, as having to look it up through commands can be quite 
tedious if you have a lot of items to check.  This would make it easier to know what can be traded and what cannot, as the Starlight Festival had a lot of items that turned
out to be untradeable, but there was a small handful that were, but they weren't obvious.
