This a small maintenance patch, released to fix a balance problem with minigunners. Thanks to Rushin' Russian for finding and reporting it!

MINOR

• Minigunners are now stunned for a short while by alien melee
  
• Fixed typo in Airdrop description
  
• Capped maximum number of sounds playing at once (hopefully will fix audio crashes)
  
• Added hidden setting to scale UI for very large monitors
