Changes since 1.3:
- added output section to config.  Now all text outputs can be configured.
- changing of the channel topic now configurable.
- whoever starts the pug can be automatically added to the pug; this is configurable.
- added two optional items to be described when starting the pug, eg: !pug 8 TDM dm6 (and output to go with this)
- output of pug details to IRC as the teams are scrambled.
- when someone joins the channel and a pug is started, and places are available, they are noticed with the pug details.
- when the pug has been started the game event is now reset automatically.
- team1 and team2 colours now configurable.

Changes since 1.2:
- changed config maxPlayers to defaultMaxPlayers
- changed !pug to accept number of players. Eg: !pug 10 (for a 5v5) or !pug 6 (for a 3v3). Just !pug on it's own will use the value set in maxDefaultPlayers

Changes since 1.1:
- added !pug command to start a pug off (rather than just joining).
- added topic changing (if bot is allowed to do so), and resetting when pug gather is done
