NGA 2023 update

Just in time for NGA 2023 😎 [list] [*] Chase distance reduced for skeletons (for the sake of game balance) [*] Gallery automatically enters pages [*] Fixed a bug where infinite players would spawn on game end [*] Made player control of a turret be first-come first-served until that player gives up control [*] Made camera change to perspective from orthogonal on game end for more visual flare in the effect [*] UI wheel now also has a toggle button [*] A short controller/input tutorial now plays at the start of a round [*] A short skippable intro movie is shown when game is booted up [/list]
