Updated to allow for pausing when losing focus.
Scanline process updated to do less things per cycle.
Control now checks for window focus.
Added additional parameters to be loaded from cfg.
Update README
Integrating a number of changes made long ago:
- Scanline optimization.
- Added more elements to the cfg script.
- Game will now 'sleep' while not focused. Less resources used while in the background.
- Updated README.
Added minimum fallback for missing assets. Spacefuck will successfully start without assets, but it will not be pretty.
Added a small sys.exit clause at the end. When we start policing dangling files, we'll ensure that everything is shut down in that clause.
