Obsidian pressure plate recipe added, obsidian ladders
Obsidian devices now have the functionality of having increased delays when it comes to deactivating (Just the Pressure Plate/Button implement this functionality in general).
Item/Block ids will only be initialized if it is actually enabled.
Fixed the initial obsidian hardness value, still modifiable. (Used to init as 0.0 as a result of stupidity...)
Fixed BlockLeverObsidian inventory texture.
