General optimizations and some QOL changes

Hello people! Hope you are having a great summer. The weather here has been absolutely dreadful so I've had some time to implement some improvements for the game.

Patch notes:

• Reduced texture sizes across the board, visual impact should be minimal. Due to this the game install size has been reduced by about 50%
  
• Loading times should be drastically improved for low spec machines.
  
• Asynchronous map loading between rounds
  
• Increased the server timeout delay which caused client disconnection between rounds in some scenarios
  
• Camera now follows a ragdolling player (only when knocked out)
  
• Reduced shader complexity for some materials
  

That's it for this update.

Cheers.
