Explosion: allow the normal blockupdate mechanism to deal with explosions

Browse Source 
in PM4, all blockupdates are buffered, so the old 7x performance penalty that used to be incurred by doing this is no longer a problem.
Also, this actually reduces the overhead of explosions themselves by moving the onNearbyBlockChange() burden off explodeB() and into the main world ticking function.
