Fix q eating barrels

[McSnaipa]

Really, why barrels level all the shit i put in to the lowest q? Like, i've filled a barrel with flour with q between 12 and 14. Once i filled it up, it ook out some flour and it was just q12. All of it! Pls jorb halp, make barrels give out an average q item

+1 to making all containers average out contents. Kinda stupid that it would make something q 100 be q 5 if a q 5 thing were put in.
