Fixing Issues...

- #672 (default user:// in $HOME/.godot/app_userdata (linux/osx) and $APPDATA/Godot/app_userdata (Windows)
- #676 (draw both tiles and octants in order from top to bottom, left to right )
- #686 (unicode escape sequences work now)
- #702 (was not a bug, but a test was added to see if bodies went too far away)
