Adds a new buyable ammunition crate to the vendor for all ammo types categories that have 2 or more different ammo types. This funbox has the same ammo count as a normal box but has a completely random amount of each ammo type, when split into a stack of whatever ammo it contains by opening it as usually, it will be a stack of 1 type of ammo, the bio of this ammo is 'looks like the engraving on it has worn away, you cant decipher the inscription. This should be fun' and the ammo will look like the type of ammo it is but have no colour. Meaning when loaded into your gun and shot, you don't know what will come out of the other end.
Also a side not: the ammo could have randomized modifiers (+ or - a certain range, different for each ammo type) so each individual random bullet will be + or minus anything between 1 and 10 DT% modifier for example.
The first part of this suggestion is my mandatory idea but the second could add more fun.
