Remove RNG from armor

Remove RNG from the premises remove from armor REMOVE. Armor now reduces damage by the percentage listed, instead of randomly deciding to half or full block damage by those percentages.

Interestingly enough this means that armor will shorten stuns EDIT: VISIBLY. Armor always had a chance to stop/half stuns, this just makes it a percentage, just like the damage. It's nearly impossible to keep a guy in riot armor knocked down, even with an e-sword. A baton would probably not be much more helpful.
