Add ability to query server list of alive players names, age and gender

[connorhsm]

An external application should have the ability to open a socket with the server to query a list of the current alive players names, age and gender.

This functionality could be used by external services such as our Discord bot Dictator or OneLifeWeb to create a display of current living players.

Dictator and OneLifeWeb is already able to achieve a similar goal by querying the server for a player count. Seen here and here.

will it be public or does it require some kind of basic authentication(token...) and which type?

[connorhsm]

Public, no authentication is fine.
