Improve the "move and equip items" button

[Mijago]

The "move and equip items" button never got much attention from me.

To do:

1. Check if there is enough space in the armor slots, if not, move one item away
2. Move the items into the inventory.
3. Equip the items.
4. Unequip mods on these items.
5. Equip required mods and artifice mods.
