Fixed some exceptions for StatusEffects with no stats assets
Added a basic stun field to StatusEffect, just locks off all input (except UI) right now (needs some effects, it looks like the game locks up)
Instead of just putting all of the examples onto Poison, made a few other examples to showcase actual functionality:
-ProtectionBuff raises all damage protection values to max
-Stun
-Weakness temporarily lowers the max HP and Stamina by 50
