Update 4.2.0 - Remove Weapon Attachments

@BaronVonGoon Good too see you too - I just said hello in your thread as well 😃

@NazT55 is spot on here as there have been a fair few requests from players who just want one attachment in each slot. At the mo you can't remove them when they're added, just change them to something else, so this should mean that people can tidy up the Plus menu a bit.
