Remodeled the junk basement

Now junk basements spawn with furniture randomly thrown around them and way more useless stuff, as well as with a very small chance of having a safe with guns/ammo on it. Makes the place considerably more interesting. 

By the way, this is basically a 60 line tall else/if block. I don't know if its actually merge worthy but I have no way of knowing unless I try;  at the very least I learned a few things about drawing squares with for loops, a win in an case.
