Multiplayer Flight Leader Selection

SU5 update:

Now with the “Local Players” interface in the Pause menu, the work is half done!

Now it just needs a button right under Add Friend for changing color.

  • The setting should stick at least until you quit the app (or possibly timeout after 24h? if you have to reload from ctd into a group then the colors are still active)
  • Colorized players should always be visible (within distance limits) even if there are too many other local planes
  • Possibly limit colorizable players to 10 or so.
