As the title suggest, making a mass discard button to go along side of the bury checked and bury everything buttons.

For when you have say...a bunch of scar decorations you don't want and discarding them all. It would be so much easier and less stress on the hands/fingers to go through and click the check box and hit "Discard checked" And of course give the prompt of "Are you sure you wish to DISCARD these items?" so that there is no confusion and gives people a chance to double check the items they have checked so nothing important is accidently discarded.

Addon edit: YES I am aware there is a "Discard whole stack" button for items but even after clicking that you still have to scroll down again/go to another page to once again click the item you want to throw out and hit "Throw out" or "discard whole stack" again for each individual item.
