Added awaitEvent() & getFriendStatus() + Temp fix for missing INITITAL_INVITE

[Terbau]

• communicator.awaitEvent(event, filter, time)

// awaitEvent(event, filter, time)
// event = communicator events
// filter = function that returns bool
// time = Milliseconds before auto-shutdown and error 'TIMEOUT' is raised

const filter = m => m.friend.id === 'fortniteId';
try {
  let message = await app.communicator.awaitEvent('friend:message', filter, 60 * 1000);
  console.log(message.message);
} catch(err) {
  console.log(err)
}

• communicator.getFriendStatus(id)

let status = await app.communicator.getFriendStatus(id);

• Temporary fix for missing INITAL_INVITE.
  This works by creating an invite from status properties
