[users] Simple Gemini server for testing in the current directory?

  I wouldn't say it's unique, just rare.  GLV-1.12556 [1] is also easy to expand
but instead of looking for executable scripts [2], it uses Lua's module
system.  These modules [3] used to return the data as Space-Age, but I
switched to a streaming model to save memory usage [4].

[2]	With GLV-1.12556, executable scripts are treated as CGI scripts.

[3]	And it's *all* modules---even serving up files from a directory is
	done using this mechanism.

[4]	Some resources served up by my server can be quite large.
