Rewrote lobby to unify common and Doom-specific packet structure, allowing for saner handling of in-game joining. Added a new per-client stage system that allows individual clients to be handled at a time when gathering and sharing info. Reworked lobby UI to display user info and added kick/ban functionalities. Bans are only a temporary per-game IP ban (use passwords to keep unwanted users out). Increased max player count to 64 and unified engine constant.
Rewrote netcode to be more stable and functional. Packet-server mode has been restrategized and will now be the default netmode when playing with 3+ non-LAN players. TryRunTics has been cleaned up with older tick control behavior removed to account for the rewritten renderer. The main thread is now more consistent when playing online to prevent potential slow downs and lock ups. Load barriers are better accounted for to prevent spikes on level transition. Improvements to chat and lobby systems including a force start game button. Added a suite of new host options such as kicking and controlling who can pause the game. Max players increased from 8 to 16 since the new code can now handle it.
Note: Demo functionality is untested. This will be rewritten at a later time alongside improvements to GZDoom's playback features (e.g. freecam mode).
Added "game in progress" message for players trying to join late. Improved "unknown host" packet logging to only log when truly unknown. Correctly abort network window so game can process fatal errors instead of hanging on waiting to connect. Unexpected disconnects in lobby now correctly update the state of the game.
* for Strife the game palette must be loaded before the start screen.
* increase update frequency of start screen to roughly 35 fps
