Rules:
  No spam
  No offensive messages
  No impersonation
I will delete anything that breaks the rules.

  !refresh
  Refresh the messages. This will remove deleted messages.
  
  !say|stuff
  Say 'stuff' in the chat. This is mostly useless, but
  people who know a password can use it to do spoopy stuff.

  !id|msg
  Get the id of the poster of a message.
  msg is the number to the left of the message.
  This will print the user id.
  
  !run_other|pw|who|command|args
  pw is the password. Only admins know the password. who is who to run
  the command on. It can be in a few formats:
    username - everyone with that username
    !username - everyone except people with that username
    @id - everyone with that user id
    [email protected] - evryone except people with that user id
    
  command is the command to run. If it was say, it would say something.
  args are the parameters to run the command with.
  
  For example:
    !run_other|password|Clarence|say|hi
    would make every user named Clarence say hi.
    
  !mute|who
  Mute a user. You can't see what they say after this
  But you will have to refresh to remove their previous
  messages. Don't try to hack around this, it's client side.
  
  !unmute|name
  See above.
  
  !exec|code
  Run the code 'code'. Don't try to hack with this, it'll
  only do it to you.
  
  !who
  Shows who is in the room.
  
  !refall|pw
  Password protected (can cause lag). Refreshes everyone.
  
  !change|room
  Move to the room 'room'. You start in 'lobby'.
  
  !room
  Get the current room.
  
  !kick|msg
  Kick YOURSELF.
  
  !color|color|attrs|text
  !c|color|attrs|text
  Say colored text. color is the color.
  attr is the abbreviations for attributes:
    b: bold
    d: dark
    u: underline
    l: blink
    r: reversed
    c: concealed
  So bu would be bold and underlined. Leave attr empty for no attributes.
  text is just what to say.
  
  !pmc|color|attrs|user|text
  Colored pm.
  
  !colordefault|color|attrs
  !cd|color|attrs
  Change your default color. See above for uses.
  
  !announce|pw|text
  !a|pw|text
  Say text in all rooms. Password protected.
  
  !cannounce|color|attrs|pw|text
  !ca|color|attrs|pw|text
  Colored version of announce
  
  !namec|color|attrs
  !nc|color|attrs
  Change your name color. Similar to other color commands. Red is password protected.
