Weapon/Vest Attachments Fix

[ozen-m]

Changes a couple things:

• Use attachment won't be stripped chance config from the server (chanceNoAttachmentsTakenPercent) before stripping weapons of attachments
• Only roll and delete moddable attachments

Issues/Todo:

• minAttachmentRoublePriceToBeTaken config from the server is not taken into account. Even low value attachments can be removed
• Helper used to figure out if attachment is moddable does not use _props.toolModdable. I'm however unsure how this is used in live
