Check Version on Login

[Papix 6461]

Hello community,

Checking the game version made by ymir never really entered my mind.

I decided to put the game version confirmation in the login as it makes more sense in my eyes.

With this measure you will no longer have players saying "I can't log in, I'm going straight down".

Nobody don't want compile source in every version change so you can add simple config.

Config.cpp

short g_NewClientVersion = 0;


		TOKEN("client_version")
		{
			str_to_number(g_NewClientVersion, value_string);
			fprintf(stderr, "CLIENT_VERSION: %d\n", g_NewClientVersion);
			continue;
		}

Config.h
  
  extern short g_NewClientVersion;

input_login.cpp
  
	if (pinfo->NewCheckVersion != g_NewClientVersion)
	{
		TPacketGCLoginFailure failurePacket;

		failurePacket.header = HEADER_GC_LOGIN_FAILURE;
		strlcpy(failurePacket.szStatus, "VERSION", sizeof(failurePacket.szStatus));
		d->Packet(&failurePacket, sizeof(TPacketGCLoginFailure));
		return;
	}

and change int NewCheckVersion to short NewCheckVersion, bcs which crazy guy will make 1231312312 the version.

Instead of using #define and (int)NEW_CHECK_VERSION (wtf?) you can use constexpr int.
