Filemanager

It will be cool to users to edit files with procedures. For example preload some maps or worlds in mcreator and when player joins the world, the map will be replacing the existing one. Another thing is to create a config files. And the best for me especially will be file reading. I can create my own litematica with this. For example I just need the same functionality as text procedures to the file. I could have done a lot more with this. Hope to see something like this in future updates
