Own LAN server not seen by remote player

[Laz]

Discovery's launcher blocks attempts to connect to none official servers. This was a dumb idea to prevent admins from regaining control during the dev coup. I removed this functionality in my open source version: https://github.com/LazDisco/DSLauncher/releases

You can either download that with the steps listed here, or you can wait a few hours and I'll upload a new version there that has a couple of updates. (If you follow all the instructions, it should auto-update either way.)
