game-shell

Note 1: Meant to be both a shell and also starting base for games. In shell mode it loads PCK files such as assets, game, lobby-client, and store. In game mode you extend the scripts and scenes such as data_bridge and the shell replaces the defaults with the new. You export as game.pck. Note 2: When converting to use as 'game' project, shell.gd and shell.tscn need to be renamed to game_core.. Note 3: Input mapping need to be duplicated between the shell and game projet.godot files. It's cleaner than trying to duplicate Godot internals of input mapping.
