serVis is not handling over the server config parameters

[kbzsl]

I was trying to set the the host to 0.0.0.0 (to listen to all IP addresses), but this parameter is not passed over to the servr::httd function.
For example, the
serVis(d.json, host = "0.0.0.0")
is not working (the same applies to any server config parameter).

Only the directory parameter is passed to the httd function:
servr::httd(dir = out.dir)

The ... in serVis() are passed to gistr::gist_create(), but you could do this:

serVis(json, "myvis", FALSE)
sevr::httd("myvis", host = "0.0.0.0")
