Server name sometimes goes blank (or to a single letter or other unwanted string)

Happends with custom maps. I have not seen this happen with official maps.

To reproduce: load in a map and check the server name.

From Discord:

If you host a map with a longer mapname it'll mess with the server name.

We'll need to protect from it in OpenNox. It's likely a simple strcpy again which doesn't check for the buffer length.
