Satako

Satako is my library for modding. I use it for many mods. It also adds 4 commands to the game: 1. `killall` - similar to kill, lets you specify namespace and path separately 2. `removeall` - same as `killall`, but removes the entities instead of killing them 3. `give2` - same as `give`, but lets you specify the namespace and path separately 4. `summon2` - same as `summon`, but lets you specify namespace and path arguments separately.
