All of my minecraft items disappered, but?

Ok so all of my items disappeared from my world because I logged into my 1.8 snapshot world with 1.7.9 and every item I placed inside a chest or in my inventory is gone. That's not my question though. I want to know if all of the items inside the chests of dungeons and temples are now emptied as well. I, for one, think they will not be emptied because they are a part of the worlds natural generation, but I really want a second opinion.

All minecraft items disappeared?

Ok, so here is the story:
I couldn't wait for the new 1.8 update, so I decided to make a world using the latest snapshot (14w21b). I got pretty far in the world and got a lot of chests filled up. Yesterday, I was playing with a friend on multiplayer (Version 1.7.9) and she was doing something so I decided to play on my single player world for a while. I logged out, still on version 1.7.9, and logged into my practically 1.8 world with an earlier version installed. I immediately noticed that I had no items in my inventory, and all of my armor was gone. Upon further inspection, every item from my chests and furnaces had disappeared as well. I assumed it was because I was on a non-updated version, logged out, got back onto the 1.8 snapshot, and logged back into the world. Still, everything is gone. Honestly, I don't care if I can't get that stuff back, it's just that I spent a very long time building the house on that world. I just want to know if I need to give up on it or not because I won't start a new world until I know for sure I can't fix the problem. I can't go in creative and give myself items (no cheat mode). For clarity, all of my accumulated items are gone, but the blocks I placed are not.

How to kill all mobs in Minecraft?

I want to kill all the mobs in minecraft (1.7.9) I want to kill all the mobs. Hostile mob (creepers, zombies, skeletons, etc…) and Animals (pigs, cows, chickens & sheep). But the /Killall and /butcher comands kill me, and do nothing to the mobs. Please help me! What are some commands. I usually use Peaceful mode but that doesn't get rid of animals (obviously). Please Help! I also want to get rid of them completely off my world/map, if that's possible… Please help!

FOR SINGLE PLAYER BTW!
