Re-TDD'd the player greeting event listener

* once I dug in, it was easy to add a "most interesting duration",
so you'll see "23 hours" or "59 minutes" instead of "0 days" or 
"0 hours"
* hid a deprecation warning
* moved the three framework classes to a "scartissue" package
Adds two more description types

* Prints other players currently online
* Prints when other players that were logged in since you were last on
were last seen
