Added Obsidian armor - Special features: Immovable, Flame Resistant, Health Boost (+0.75 kb resistance, Fire protection IV, +20 Health) (All pieces must be worn for those to work)

Attack Speed removed from Quartz Armor and replaced with Speed 2 since it's supposed to be Movement Speed. Don't worry, the current ones
dont need to be replaced since it'll give Speed 2 anyway!
Note: Any potion effects from any armor will OVERLAP/REMOVE the current effects (if they are the same potion effect)
e.g You have speed 5. You used quartz armor, and it'll be replaced with Speed 2!

(I am gonna slightly work on this plugin)
