[1.1.2]The Magma Canyon

All bugfixes are done, everything is balanced, including multiplayer, now! Me and a friend have did a full playthrough of the map, and I also did one in single player! After that, I'm sure there's no more bugs. ;) Along with that, I've balanced the map too! It's not not as easy to fall, and there are signs hinting where to go. I even adjusted the multiplayer version's insane spawnrate habit with slimes.

1. Multiplayer: Added stone background walls to lower spawnrate in some areas
2. Added a dirt/stone wall background to the main island so you don't get overloaded with slimes the moment you spawn
3. Fixed lack of items in dungeon/floating island chests
4. Multiplayer: Fixed dungeon problems
5. Updated signs at spawn
6. Fixed wall mistake in Sky Climb
7. Fixed not being able to escape the pyramid without placing blocks
8. Added platforms to the Eater of Worlds arena
9. Made it so that jungle mobs don't spawn outside of the jungle
10. Added tips sign
11. Marked where the dungeon is and where there's nothing left to find in a certain direction
12. Added .bak files for the people who are having errors(Me and my friends weren't, I got no idea why some people were)
