    *Functionality from Virtual Ammobox System*

    Description:
    Checks what type of an attachment is passed and what it is compatible with.
    Should now be compatible with the new compatibleItems class structure... This was not a fun task but thankfully
    Robalo gave me some code that showed me the way. If it isn't 100% compatible then IDFK. The forEach in a forEach drove me nuts and
    not the best way to do things, I really don't know what I was thinking but doing PHP code for two weeks and playing GTA V tends to make you
    forget things.... Wow what a ramble... blah blah blah.

    Returns:
    0: Unknown Error
    1: Primary
    2: Secondary
    3: Handgun
