Correct contents of varrock newspaper. Converted it to kotlin listeners.

What has been done in this MR?

• Corrected contents of varrock newspaper.
• Converted file to kotlin + listeners.

I'm checking in something I did a while back.

What should testers check?

• Newspaper should work and contents should reflect as in source: http://youtu.be/ePVNOiSzOS4

• I have tested these changes thoroughly.

• I used the relevant Thanos/Zaros tool for any JSON edits where possible, and have attached screenshots of any changes.
