VS10: Encode custom command comments for echo (#11283) 

VS10 uses MSBuild underneath.  The <Message></Message> CDATA are just
appended to "echo" and executed as a single command.  Encode the message
such that it can be passed to echo.  Convert newlines to tabs since they
cannot be printed this way.
