plasma pistol and stacks

[gaara]

plasma pistol should cost only 1 "High-Tech Components" (now it's pointless to use pistol if plasma rifle cost 5)
stacks :NaCl, S, KNO   -  should be 250 ( they are not heavier than coal or iron )

We will be completely changing laser and plasma weapons in the next update. Yes.
