v.4.0.0

🔄 Fixed almost all hitsounds of Standard mode, and some hitsounds of interface

🔄 Fixed combo break as suggested by Hikari Richiumu

- Deleted the response of hit300, hit300g, hit300k (It means the image files of hit300, hit300g, hit300k are kept, while hit300-0, hit300g-0, hit300k-0 are changed from the image with the word "G R E A T" to a 1px image in transparent)

🔄 The overlay of hitcircle is no longer translucent (If you want it to be blurred, please notify me, the next update will make it blurry)
