An idea of supporting writeCloser

[the-plate]

We could do something like this to support upload files(bytes) via WriteCloser... Any hints or recommendations are welcome.

thanks for the pull request. what are the benefits over

c := gowebdav.NewClient("/", "usr", "pw")
r, w := io.Pipe()
go func() {
   defer w.Close()
   fmt.Fprint(w, "foo bar")
}()
_ := c.WriteStream("/foobar.txt", r, 0660)

This could be handled by a wrapper function outside the project.

Please rebase on master and try to address the feedback. thank you!
