Print scheme name prefix when serving the site locally
serve command in the current version of obraz prints
Site generated successfully Serving at 0.0.0.0:8000
when the site is ready.
I propose to print
Site generated successfully Serving at http://0.0.0.0:8000/
Scheme name prefix (
http://) helps to highlight the URL as an active link in many terminal emulators (most VTE-based terminals) and text editors (Emacs, TextMate, Notepad++), and allows to open the newly generated site directly.
Also, according to RFC3986, the scheme name is not optional.
