Tweak some values (gunstats/volume)

[Fueredoriku]

• Hat projectiles must be faster
• Solar body reload doesn't work as expected
• DDR damage must be lowered a bit
• Bidding music volume should be a bit lower to be in line with the battle music
• Controller sensitivity should be lower (and maybe also adjustable)
• Shotgun ammo capacity should be a lot lower
  • Ammo should also be clamped to 1
• Have large hitboxed for gamepads
