Add app to showcase with source link

Summary:3 small changes

Added a published android app to the showcase.

Modified the rendering of the apps.
When there's a _source_ property on the app object, the link will show up as shown in this screenshot.

Also, external links have the _blank target and not just blank (without the underscore), so a new tab/window will always be opened.
Closes https://github.com/facebook/react-native/pull/5761
