Lots of server message indices are wrong

[Velaron]

This is usually not a problem, but for example when using amxmodx with gungame, it tries to send a "svc_finale" message with index 31, while in xash3d index 31 is "svc_modelindex" causing a crash.

This is an incompatibility between the protocols of the old xash and goldsrc.

Unfortunately, this cannot be fixed without breaking compatibility with old clients. But you can use SVC_INTERMISSION instead of SVC_FINALE. If you need to add text in the center, then you have to add a couple of lines of code.

There is an idea:

https://github.com/tyabus/xash3d/blob/master/engine/server/sv_game.c#L2526

In this function, it can be possible to dynamically rewrite svc_finale to something that will emulate its behavior, use both of svc_intermission and TE_TEXTMESSAGE for example. Intermission level won't be correct, but at least it would work.
