Option to set response status

[reod]

200 OK is not always wanted case.
It could look like:

Usage of ./goStatic:
  (...)
  -status-code int
        Define response status code (default 200)

I'm curious about your need to have 2XX responses status codes. Are you serving files? From what I remember, serving files that exists should answer 200.

I need to serve simple HTML with information about maintenance mode and status has to be 5XX, because other services (monitoring, etc.) need this.
