Implement a drop all button

Is your feature request related to a problem? Please describe.

With more item categories its now harder to drop everything. An easy drop all button would work, based on the existing item category selection dropping method. This would help everyone even without new item categories, it saves time and keypresses.

Describe the solution you'd like

You can currently press tab to go from dropping an item to a whole category of items. Implement it so you can press TAB again to select every item in your inventory at once, excluding favorites. Here's a screenshot so we're on the same page.

Additional context

Will alleviate burdens of dropping things into your unsorted loot zone.
