Shipping Package tweaks

Shipping packages now have sealed and unsealed icons
- These are just minor edits of the idOld icon_state the shipping
package previously used.

Shipping packages now have their own proc to handle adjusting their
description, rather than being done manually by the request console that
creates them.
- The description also reflects if the package is unsealed (just in case
the icon didn't give it away

Empty unsealed shipping packages can be destroyed by activating them
in-hand.
- There is a confirmation to prevent accidental shredding of shipping
packages.
