Some code cleaning.
Removed the "users" list as it was a duplicate of ActiveUsers...
Fixed channel name must be lower-case letters in-order to let chat messages work...
Added an option to use "online" as a target in the currency add/set/remove commands, it'll add, set or remove the online users' currency (basically how "all" worked before my changes).
Better command logging, the 2nd parameter in sendMessage is now an optional string that if set to anything but "" it will be logged.
