V21 - Housekeeping update

• Decreased install size
  
• Added a new toggle in controls to toggle between On Press or On Release of input
  
• Updated the Unity backend
  
• Implemented several translation suggestions
  
• Proper Cloud saving Cross-Platform Win/Mac/Lin now
  
• Migrating save files (copying not deleting so old one is still there) from old versions to new save location to be consistent with all my games.
  
• Removed additional exit menu and videos.
  
• Added unified Update text and "More Games By" panel on main menu that will be in all my games going forward. If you click the panel it will open to the games page and then won't suggest that game again on this installation. Also allows me to push update text without a full game update in case of urgent issues.
  
• Fixed reported bugs
  
• Updated store page and features where appropriate
  
• Resolved the broken Steam Leaderboards button
  
• Resolved crash on exit on Mac
  
• Probably other minor fixes I forgot (sorry)
