v2.34

Added the ability for users to set themselves as {prefix}afk. While in AFK status, if the user is mentioned, the invoking user will be notified the user is currently AFK. Bots are ignored.
Added the ability to see latest changes to the bot using the {prefix}changes command.
Fixed an issue where using the {prefix}8ball command would send two messages, one being an error that the command wasn't working, the other... the working command result.
Fixed a similar issue where using the {prefix}decide command would simply send an error it wasn't working. The command is now working as intended.
