mobs: add and adjust drops of livingnether mobs

Dirk requested to merge dirk/aestivalserver-mods:master into master

For some mobs drops were missing and others needs adjustment. Note that there are drops from obsidianstuff and farming. The idea was that sokas can drop an obsidian sword or even a nether sword, because they are a human like civilization. And of course the "noodlemaster" should drop noodles.
