Multiplayer improvements and tweaks

Get ready for takeoff! The latest update is now available with the following changes: • Each player can change plane armor in Multiplayer. • The host can select which planes are allowed in the session. This gives you the possibility to exclude some planes or even to create a session with only one playable plane. • We added a requested feature of enabling friendly fire in the Team Deathmatch, Co-Op, and Raid modes. • Added favorite bar in the respawn window. You can add up to 3 planes to your favorites and pick a respawn plane swiftly. • Improved particle effects like explosions, smoke, and water splashes. • Adjusted speed while landing with open flaps.
