Moderator chat

[acristescu]

Moderators have a modal chat tool on the website that they can use to communicate warnings and other important messages to the user and make sure that they are heard. The app does not support it. The websocket packet looks like this:

"private-superchat"
{
enable: false
moderator_id: 412892
moderator_username: "Eugene"
player_id: 89194
player_username: "MrAlex"
}
