Small update — Cyber Sentinel Steam update #1339884

I did small update that makes these changes: - fixed tutorial error reported by user piyoko - thanks - fixed volume bars - now they should work better (linear changes) - fixed missing strings in Italian translation - added shortcuts in level editor to quickly change piece type/configuration tool (try 0-9 keys) - If you have bug reports, suggestions - please don't hesitate to write! For now I'm thinking about adding more shortcuts in-game. Also thinking about adding more optimisation stats at the end of each level (states used, transitions used, simulation steps needed to finish level). What do you guys and gals think? Cheers and have fun playing!
