Greeter skeleton created by wizard
added initial README.txt
added privmesg so don't spam the channel, need to add db so we know who we've seen and normalization routine so we can handle nick variation. And of course need to add a standard message
Added very simple user database.  If the key isn't found in the database,
you get greeted and added to the database.

Still need to:

  * add a better message
  * do some nick filtering/regexing
added better greeting message
