Add a method to get a list of all active connections

[Renegade334]

class Plugin extends AbstractPlugin
{
  /* ... */

  public function myRegularCallback()
  {
    /* get some data */

    foreach ($this->getClient()->getActiveConnections() as $connection) {
      $queue = $this->getEventQueueFactory()->getEventQueue($connection);
      $queue->ircPrivmsg('#mychan', "OHAI I HAZ SUM DATA 4 U: $data");
    }
  }
}

There is the question of whether such a function would need to be added to the client interface.

Do we really need the "active" portion of the method / property names? Seems implied that the connections being managed are active.

[Renegade334]

Needs to be distinguished from the addConnection() family of methods, which create IRC sessions from connection objects. These ones just mark connection objects as active or not active by adding and removing them from the store.

Thanks!
