adds and rebalances items

adds a vest, medkit, hardhat for the mt's and the CE to help them out in the shift, limiting their gear as FOB reinforcements since any mt was able to grab a marine armor and fight as one

adds one pouch slot more to the civilian m3 vest to leave it at the same storage level of other marine armors
