Title: Update SendGrid documentation

- updated documentation to use the latest version of node.js and python libraries
- updated PHP documentation: replaced $ENV['SENDGRIDUSERNAME'], $ENV['SENDGRIDPASSWORD'] with getenv('SENDGRID_USERNAME') and getenv('SENDGRID_PASSWORD') because $_ENV isn`t working with AppFog php.ini configurations.
