Changed FillContainersOperation so that empty dispensers are not filled
with a stack of arrows on import. Just in case someone needs to use
empty dispensers in their design. As far as I can remember, this won't
affect any of our dungeons - arrow traps are rare. The only dungeon that
I can remember is one by Balgor and it was exported with all of its
dispensers loaded.
* Added a small treasure room that opens when the puzzle is solved and
made the exits in the corners slightly more apparent by placing redstone
lamps.
* Tweaked the redstone a little to correct for a brief signal cutoff.
* Tried to add fireworks that would shoot out when the puzzle was
solved, but it was too hard to secure them against theft while also
getting consistent explosions.
Updated the dungeon pistonFallRuins so that it causes less extreme lag
by slowing down and spacing out the timing for the piston traps. Also
reinforced the dungeon against tampering and added lava inside each
piston drop.
