[users] Gemini "Server of the Day" & database

[Anna “CyberTailor”]

I'm glad to announce this useless thing!

=> gemini://sotd.sysrq.in

It advertises randomly chosen gemini server for a day.
Also there's a list of all servers and SQLite database.

And speaking of database, it can be automatically updated by email.
=> gemini://sotd.sysrq.in/info/README.gmi

That's all.

(By the way, how to fix this error with PRAGMA foreign_keys:
foreign key mismatch - "server_features" referencing "servers")
