[ANN] A new gemini client for acme

[Parker Ellertson]

This client is 52 lines long (68 if you count the lines in
"displayonacme"), and as of now it's just a bare-bones client that
doesn't do any sort of TOFU authentication or self-signing certs.
There will be improvements made on it later (such as not opening
duplicate windows for the same URL) but I'm very happy with the way it
is now.  The GitHub link is at the bottom, and there's probably a bug
or two.  I'm going to continue work on this so that it's top-notch.
