GIT_SILENT: Update source code license headers.

Thanks to Eric Newberry (from Google Code-In) for running the heavy
lifting on this.

I made some other corrections since we're touching all the source
anyways (e.g. fixing my email addresses), fixing the encoding of Richard
Lärkäng's name, and I've also chosen to avoid the fancy box-shaped
comments so that there's no issue with trailing spaces/tabs.
