Sammyall's Werewolves

--- CHANGES ---

Changed how "____ Helmet of the Werewolf" works:
* Now has the buff last for 40 seconds, however reapplying it every 20 seconds!
* This prevents the extra health and stamina from being removed like it was for the last version.

Changed "Potion Of ____ Wolves" and "Potion Of Werewolves"
* Their effects now stack. So if you drink 3 potions, you will get 3 minutes of said effect!

--- ADDITIONS ---

Added an Iron, Thorium, Cobalt, Adamantite, and Mithril "____ Helmet of the Werewolf":
* Acts as its exact tier of armor would, apart from the benefit of the werewolf buff.

Added "Potion Of White Wolves":
* +15 Max HP
* +2 Max Stamina
* Same recipe as "Potion Of Black Wolves"

Added "Potion Of Grey Wolves":
* +15 Max HP
* +2 Max Stamina
* Same recipe as "Potion Of Black Wolves"

Added a "Sammyall's Werewolves" tab in the Armour's Workbench and Alchemist's Workbench:
* These are at the ends of the table. I wanted to add them to declutter the tabs they used to be in.
* If need be, I'll add my own bench for all my items later if there are conflicts with other mods because of this.

--- KNOWN BUGS ---

-/-Major Bugs (Any that either come from Hytale itself, or I genuinely have no idea.)-/-
The buffs from the helmets now have a 20-second cooldown. 
This now prevents it from being reapplied for some reason before the 20 seconds are up, even if the effect is cleared.
