M4 Synthetic PMC 'armor' changes p1

[QuickLode]

About the pull request

this is #4758 but atomized, this one only changes code, next one will only change sprite. the conflicts involved with sprites was quite ridiculous

Basically M4 PMC Synthetic 'armor' stated it offered 'maximum protection' even though it offers quite literally 0. Furthermore this complete lack of protection does not constitute the 20% slowdown netted.

So I'm fixing the description to state clearly that there is NO ARMOR OFFERED and furthermore, lowering it to a 10% slowdown(Justified by having 1 extra storage space?). I think this is a step in teh right direction for now.

10% comes from a new category called SUPERLIGHT which will be used for this only atm. May go to other stuff later.

Explain why it's good for the game

Description should match what an item offers and not be misleading. If it says it has armor - it should have armor. If it isn't gonna have armor, it shouldn't say so.

Next, 20% slowdown is A HUGE price for 1 single storage slot. Its almost ridiculous. Hopefully 10% is better :)
