Disk-Space Upgrades for PDA

[Erik]

Just shoving this into cartridges.dm should do the trick for a large cart, i wanted to do a patch with some of the other ideas in this topic but someone bribed me to write something else.

Code:

    extra_storage
        name = "Storage-Master Cartridge"
        desc = "There is a torn 'do not ingest' sticker on the back"
        icon_state = "cart-s"
        file_amount = 1024

        New()
            ..()
            src.read_only = 0
