v[1.0.24] Stockers take boxes from the floor

Stockers take boxes from the floor

One of the most requested features is now out :)
Stockers take the boxes from the floor anywhere in the game and then fill the racks in the store.
When there is no store-rack-filling job in the store, they fill the warehouse racks.

Stocker Levels

Here are the new level requirements for stockers:
1. Stocker Level: 10
2. Stocker Level: 17
3. Stocker Level: 24
4. Stocker Level: 31
