Maximum number of GRFs that can be sent.
This limit exists to avoid that the SERVER_INFO packet exceeding the maximum MTU. At the time of writing this limit is 32767 (TCP_MTU).
In the SERVER_INFO packet is the NetworkGameInfo struct, which is 142 bytes + 100 per NewGRF (under the assumption strings are used to their max). This brings us to roughly 326 possible NewGRFs. Round it down so people don't freak out because they see a weird value, and you get the limit: 255.
PS: in case you ever want to raise this number, please be mindful that "amount of NewGRFs" in NetworkGameInfo is currently an uint8.
