Minor Fixes

[SweptThrone]

Today, I've fixed and improved a few things:

Fixed Guards being able to respawn instantly.

• I was not setting the respawn time to be relative to the current time.
  

Infiltrators now always have a white coat again.

• The default model was updated to use the player color system, meaning Infiltrators would be colored with their player color instead of just white.  They will now always be white.
  
• Guards still use their player color, however this only affects the scoreboard and location pings.
  

The full camera image will now always be shown on-screen.

• Since the render target is rendered at an aspect ratio of 2:1, the edges would be cut off on displays with a lower ratio, effectively lowering the FoV of players with standard 16:9 monitors.  This is now fixed; aspect ratios greater than 2 are pillarboxed as always, but aspect ratios less than 2 are letterboxed.
  

Spectators no longer stay freezing.

• Previously, freezing was not reset when a player became a spectator.  Now it is, so the freezing overlay will not appear when spectating.
  

Loadout music now only plays the first time the menu opens, which is automatically at the beginning of round preparation.

• The music also no longer plays when hitting F3 mid-round.
  

The following change is from August 10:
Fixed Team Krilla not properly counting damage.
