Persistent startup port and options

[nx10]

[...] For users who would really prefer to not type in ports and/or tokens each time, you might consider adding options, where the defaults are sane (allowing them to set personal prefs in ~/.Rprofile):

httpgd <-
  function(host = getOption("httpgd.host", "127.0.0.1"),
           port = getOption("httpgd.port", 0L),
           width = 720,
           height = 576,
           bg = "white",
           pointsize = 12,
           system_fonts = list(),
           user_fonts = list(),
           recording = TRUE,
           cors = FALSE,
           token = getOption("httpgd.token", TRUE)) {

In related packages, I've found it useful when the "random port" remains constant for the current R session. It's not hard to do: generate a random port and token in .onLoad and/or you can use a local({ ... function(...) {... } }) trick for a function (likely httpgd::httpgd).

... though I think it was actually fixed with b97eedad5fd039046d8b96c0e4f3682c958b3649 :-)
