Changelog 07.05.23

So, I'm back to working on Avoider, since it's already mostly done, it should take too long to finish, but unfortunately I'm also busy with other stuff.

Changes:

• Added a settings menu on pause
• Game pauses when you click the mouse outside of it and it loses focus
• Fixed controls sometimes getting "stuck" forcing the ship to keep moving in the same direction
• Added stereo sound
• Added some sounds(shooter charge, bomb preparing to attack)
• Split CSS into separate files
