[arlina-espinoza]

Add at least an automated test class to verify the distribution under the following installation options:

• Setting the Apigee Connection settings
• No monetization
• Enable demo content

Verify the following:

• Frontpage loading with featured APIs, main menu links, account links (apps, my account, logout).
• Viewing an API Doc page: making sure SmartDocs widget is rendered.

Depends on #418.
