improved TNT exploit prevention 

Now, canceled exploit attempts don't injure players or mobs as if the TNT had successfully exploded, and if it's the case of an existing TNT block which a redstone torch is attempted to be placed next to, it no longer drops a free TNT item. In that case, the existing TNT block is still destroyed itself, but... oh well, it's close enough to perfect.
