Made stepping on Redstone Ore fire PlayerInteract events for players, EntityInteract events for other entities. Fixes BUKKIT-1163 and fixes BUKKIT-1182

Note: the client seems to predict redstone ore interacting, so you may see
ore lighting up when it shouldn't be. However, cancelled events should
function as expected.
