[PR] Add extra items to security closets

[Chasu]

Flashbangs are replaced? I'd assume it's because of how strong the combo can be, seems a bit odd though Also not a massive fan of the Headsets being there but I don't care a whole lot, if people want them there then sure, I guess it makes sense with how public most of the lockers are.

Yeah, there were come concerns about the flashbang-riot launcher combo, but out of all the changes, it's one which I care less about.
