+ Added alternate nick configuration parameter. Using it if the bot's nickname is already in use has not yet been implemented.
+ Commands can now be typed lower/upper/mixed case
+ Fixed two error messages (were missing endlines so they weren't sending)
+ UDD no argument error message is now sent to the chat where it was request, not the lobby.
+ Fixed command UDD without a param so it doesn't trigger an exception because of line[4] out of range.
