added future project files
added data emitter instead of console logging

added an emitter instead of direct console logging for sent / received
data for future project
updated example to reflect irc.js change
updated auction open / close logic

better auction logic. open: now checks if an auction is already open and
outputs the appropriate message (prevents bids from being removed when
opened again). close: now checks if there are any bidders in the bid
list and outputs the appropriate message if empty.
added check for a called command

now checks to see if a potential command was called (! being the first
character in the first array item). this prevents unnecessary calls to
the database.
