Opening of the first modules a new Gemini station

[Gregory Chamberlain]

I think the idea is to put a single character, emoji or otherwise, in
/favicon.txt to be displayed as your capsule’s favicon in browsers that
support it.  This is analogous to /favicon.ico on the Web.

I’m not aware of any formal standard so I guess it’s more of a
convention, at least for the time being.  In any case, a missing
/favicon.txt is no crime.
