Summary:
Ref T12573. `JX.Leader` synchronizes the Aphlict connection across multiple windows.
Currently, we only test to see if the leader window has been closed every 16 seconds. Instead, test every 1.5 seconds.
Also, make windows keep trying to become the leader forever. This was removed previously (in D15806) but I think that change decreased robustness here.
Test Plan:
- Opened two windows to the "Realtime" tab in DarkConsole.
- Saw one become the leader and one become a follower.
- (Optionally, wait for 10 seconds here to test the "keep trying to become the leader" behavior.)
- Closed the leader.
- Saw the follower become the leader after ~1.5 seconds.

Summary:
We're sometimes getting duplicate notifications right now. I think this is because multiple windows are racing and becoming leaders.
Clean this up a little:
- Fix the `timeoout` typo.
- Only try to usurp once.
- Use different usurp and expire delays, so we don't fire them at the exact same time.
Not sure if this'll work or not but it should theoretically be a little cleaner.
Test Plan:
- Quit Safari, reopened Safari, still saw a fast reconnect to the notification server (this is the goal of usurping).
- Did normal notification stuff like opening a chat in two windows, got notifications.
- Hard to reproduce the race for sure, but this at least fixes the outright `timeoout` bug.

Summary:
Fixes T10697. This finishes bringing the rest of the config up to cluster power levels.
Phabricator is now given an arbitrarily long list of notification servers.
Each Aphlict server is given an arbitrarily long list of ports to run services on.
Users are free to make them meet in the middle by proxying whatever they want to whatever else they want.
This should also accommodate clustering fairly easily in the future.
Also rewrote the status UI and changed a million other things. 🐗

Summary:
Ref T6559. Adds a "JX.Leader" primitive to replace the synchronization over Flash. This does a couple of things:
- Offers an "onBecomeLeader" event, which we can use to open the WebSocket.
- Offers an "onReceiveMessage" event, which we can use to dispatch notifications and handle requests to play sounds and send desktop notifications.
- Offers a "broadcast()" method, which we can use to send desktop notification and sound requests.
Test Plan:
Added some code like this:
```
if (!statics.leader) {
statics.leader = true;
JX.Leader.listen('onBecomeLeader', function() {
JX.log("This tab is now the leader.");
});
JX.Leader.listen('onReceiveBroadcast', function(message, is_leader) {
JX.log('[' + (is_leader ? 'As Leader' : 'Not Leader') + '] ' + message);
});
JX.Leader.start();
}
```
Then:
- Saw first tab open become leader reliably in Safari, Chrome, Firefox.
- Saw new tab become leader reliably when the first tab was closed.
- Saw broadcast() work as documented and deliver messages with correct leadership-flag and uniqueness.
