Free upgrades! Replacement items not removed from inventory.

[okradonkey]

Describe the Bug

Mouseover upgrade planner is free; installed items are not removed after upgrading via upgrade planner + mouseover.

To Reproduce

This applies to any items, but we'll use belts for this example.

1. Acquire 5 yellow belts and 5 red belts
2. Install a row of 5 yellow belts
3. Use the upgrade planner to mark yellow belts for upgrade to red belts
4. Mouseover the yellow belts, upgrading them to red belts
5. The 5 red belts are installed. In your inventory, you now have 5 yellow belts AND 5 red belts.
6. The 5 red belts should have been removed from your inventory.

Proposed solution:

In control.lua, in the upgrading section (approximately line 85), add the following line to remove the upgraded item after a successful upgrade. I believe this will solve the issue. Thanks!

                if upgraded_entity then
                  player.play_sound{
                    path = "entity-build/"..upgraded_entity.name,
                    position = upgraded_entity.position
                  }
>>>               inventory.remove(use_item)
                end

How did I forget that? Thanks, fixed for the next release.
