applied in that change. They are small documentation fixes and a
switch from using fmt.Fprintf/os.Exit to log.Fatalf.

Without changing the behavior of the present command for local
usage (using the local socket for running examples, defaulting to
the current directory for all content). Add flags and set them to
the appropriate values if running on App Engine.
Notably, since the Go files must be in the same directory as
app.yaml, the content root must be ./content/ to avoid listing
the present source files.
It also defaults to running example snippets via the HTTPTransport
(https://play.golang.org/compile) instead of locally when on App
Engine.
There are also some small cleanup code changes.
