Add missing calls to BlockRedstoneEvent. Adds BUKKIT-3926

This adds calls to BlockRedstoneEvent for the new daylight sensor and
trapped chest blocks. Note that the redstone level for trapped chests
cannot be modified, as it is based on the number of players currently
viewing the chest's inventory.
