Add QuickVerseLookup example for beginner JSword users

[Arcturus742]

I want to contribute a simple example class QuickVerseLookup in the org.crosswire.jsword.examples package.

This example:

• Looks up a Bible verse (default: John 3:16) using Book + Key APIs
• Demonstrates how to print canonical text returned by JSword
• Shows how to handle missing modules more gracefully (e.g., missing KJV)
• Can serve as a template for small tools (verse-of-the-day, sermon helpers, etc.)

This will help new developers and ministries quickly get started with JSword.
Thanks for considering this!
