Now the game pretty much supports modding. MainScene will now look through the project opening all files named game_module.tres and in alphabetic order of their resource_path if exist it calls load_module on them. ESS's resourcedb is now created by MainScene, and it's the static type, with id remapping on. Append your resourcedbs into it. See game_module.gd. Also updated HEADS to grab the latest ESS.
