Fixes for conscript.lua Created spamlevel.lua

* Conscript.lua wasn't sending some changes to the units... due to c&p
stupidity. All 'unit.' are now properly 'v.'
* Spamlevel.lua is for being EVIL to df. Specifically 1 full z level. While
there are probably better ways to do something this evil and stupid, I do
not personally know them. Thus this !@#(lazy)#@! iterator.
