Add option to strip advanced copy paste info out

[Regisle]

This fixes 2 issues, it fixes the issue that items are still added to the display and parsed even if you dont want them to, which can cause crashes, and this allows you to strip the advanced info out so you dont need to go recopy the item.

The UI could use work (better wording/spacing/sizing of elements), and it might be a good idea to move the popup code out of Items Tab inputEvents to its own class function.

I also want to add an option in future that converts an advanced copy paste to a pseudo crafted item, where you can easily adjust the mods or the roll ranges, but that is out of scope for this.
