It appears that the settings `escoria/esc/command_paths` and `escoria/main/command_directories` have duplicate purposes. Unfortunately, they are read in different places, so if you add a directory to one setting, it will not be present in the other. Specifically, `ESCCompiler` read from `escoria/esc/command_paths` while `ESCCommand` and `ESCCommandRegistry` read from `escoria/main/command_directories`. As the `COMMAND_PATHS` constant had no references, it seemed more appropriate to delete. The `escoria/esc/command_paths` appears to have been set initially in `project.godot` as part of: https://github.com/godot-escoria/escoria-demo-game/pull/467
