Create call-to-action message during Drupal installation process

Idea

Create a call to action message during Drupal's installation (while the db is being configured).

What this issue is not

This issue is not to debate what the message *should* be, it's just to get sign off on the fact that a message can exist.

Possibilities (not to be debated here)

Lots of great possibilities here including

• Have a default message stating, "Drupal is much more than software, we have a whole community', or "Come checkout Drupal Conferences", or "Join the Drupal Association", etc.
• Have the installation attempt to download JSON and display a message (we could do A/B testing to see what works best!)
• Do Geolocation, and display a list of upcoming Drupalcamps and cons!
• Display a list of new feature in 8.x (remember the messages during Windows installations when upgrading?)
• Etc Etc.... but let's not debate this now

Process

When we get signoff on this, we'll create an issue and come up with ideas. Then the community can bikeshed for a certain amount of time (while being publicized). While that's going on, we can start the technical processes. If we're downloading JSON to the client, this will require changes to Drupal.org

Genesis

This idea was originally @mtift's, and he stated it at the end of the most recent Lullabot podcast (MP4 attached for posterity).
