add option to literally throw away items if the bot is unable to pick up an item

## Describe your suggestion
an option that when enabled (and depends on `mineScanDroppedItems` (maybe? probably)), will drop a slot of items from the inventory, assuming that the item is within the list of the setting `acceptableThrowawayItems` to make space available for picking items up.

## Settings
`throwItemWhenFullInventory` but there could be a better name that better describes the setting.

## Context
when `mineScanDroppedItems` is enabled, it attempts to pick up items. when it can't pick up the item, the bot stalls.
the bot will stall until the end of time, or more accurately, until the item despawns.

## Final checklist
- [x] I know how to properly use check boxes
- [x] I have not used any ___'s or ___'s in this issue.
