*
* Usage:
* Chat.parse(message, room, user, connection)
*
* Parses the message. If it's a command, the command is executed, if
* not, it's displayed directly in the room.
*
* Examples:
* Chat.parse("/join lobby", room, user, connection)
* will make the user join the lobby.
*
* Chat.parse("Hi, guys!", room, user, connection)
* will return "Hi, guys!" if the user isn't muted, or
* if he's muted, will warn him that he's muted.
*
* The return value is the return value of the command handler, if any,
* or the message, if there wasn't a command. This value could be a success
* or failure (few commands report these) or a Promise for when the command
* is done executing, if it's not currently done.
*
* @param {string} message - the message the user is trying to say
* @param {Room} room - the room the user is trying to say it in
