Make the "Warning" (value) tag searchable in a backpack

[AwesomeMcCoolName]

It would be nice if you could search for any item with a "warning" tag so you could know if there are any craft #s or odd-level'd vintages hiding somewhere in a backpack.

I approve of that

My level 1 vintage hats don't even get the warning sign D:

Probably because these tags would also appear on level 1 vintage weapons
