Fix crash when launching Zandronum via Doomseeker

Added the CVar sv_terminatorfragaward, which controls how many frags are obtained upon fragging the Terminator. [geNia, Trillster] Added mouse input type selection to MENUDEF so players can toggle the in_mouse CVAR easier and select the desired input mode. Also clarified the function of the old Skulltag mouse option. [Ru5tK1ng] Added the CVars "cl_bobrangex" and "cl_bobrangey" to allow the x/y-range of a weapon's bob to be customizable by the user. [AKMDM] Added the new MAPINFO property "gamemode", allowing maps to be locked into one specific game mode. [AKMDM] Added support for using libsecret to save auth credentials on POSIX platforms. This allows passwords to be stored using services such as KDE Wallet and GNOME Keyring. [Sean] Weapon sprites are now fully interpolated, and can be toggled with the new CVar "cl_interpolateweapons". Based on code from ZCC. [AKMDM] Added the CVARs sv_minfov and sv_maxfov to set client limits for FOV on the server. [Ru5tK1ng] Added a net graph, enabled with the new CVar "cl_netgraph", that shows changes in network traffic over the last minute, which appears while "stat nettraffic" is active. [AKMDM] Added the constants LUMP_INFO_NAMESPACE and LUMP_INFO_WAD to the "LumpGetInfo" ACS function, to return a lump's namespace and the index of the WAD it belongs to respectively. [AKMDM] Added ACS function: "GetWadInfo", to return information about a WAD file using its index. [AKMDM] Added ACS function: "SetMapUsedStatus", allowing mods to change the used status of an entry in the map rotation. [AKMDM] Added the GAMEEVENT_PLAYERJOINS EVENT script type, which triggers when a player is just about to join the game, and allows mods to prevent players from joining and queue them instead if the event's result is set to zero. [AKMDM] Added support for using Zstandard to compress in-game traffic. [Sean, AKMDM] Added ACS function: "CheckScript", to check if a particular script exists by searching for its name or number. [AKMDM] Added the CVar sv_requireskulltoscore, which controls whether or not players are required to have their skull at base to score in Skulltag. [Trillster] Added support for custom winning and losing intermission screens using the new MAPINFO properties: "winnermusic", "winnerpic", "losermusic", and "loserpic". [Barrels O' Fun] Music tracks can now be selected for team winning and losing themes (e.g. WinnerTheme "D_STWIN:1"; LoserTheme "D_STLOSE" 1), and can be used in ACS with new GetTeamProperty properties: TPROP_WinnerThemeOrder and TPROP_LoserThemeOrder.
