Implement Studio Plugins

These plugins are for an activity done in The Studio called "Artist of the Day".   This is an activity where users get to nominate their favorite artist for "Artist of the Day"-- the winner is randomly selected.  Once we choose a winner, we then go on to record that on our website every day.  These commands will aid the room with this activity in several ways, such as: If a user forgets the AOTD, they can do /aotd and it will tell them until it's changed the next time.  It will also record it in the modlog, should the server restart and no one remembers who it was, so we can later record it on the website as well.
The indentation of lines 252-259 is still wrong.
