Summary:
Fixes T5373. Ref T5281. Several changes:
- The `marshallExceptions` thing is useful if JS throws an exception when invoked from Flash, so set it. The resulting exceptions are a little odd (not escaped correctly, e.g.) but way better than nothing.
- Put connection status in the notification menu.
- When the connection fails, try to provide contextual help where we can.

Summary:
Ref T5373. The control flow between `aphlict-listener` and `JX.Aphlict` is pretty weird right now, where the listener (which is the highest-level component) has intimate knowledge of how to put the SWF on the page.
Instead:
- Make `JX.Aphlict` a real singleton.
- Instantiate it sooner.
- Have it handle the flash setup handshake.
Test Plan: Loaded page in debug mode, saw normal flow take place.

Summary:
Ref T5373. This seems to work pretty much correctly.
Also stop popping bubbles and just use the log, since users find the bubbles confusing/not useful and they're not great for developers either.
Future diffs will expose more user-facing stuff.
Test Plan: Added `throw` to AphlictClient.as, got a log in the parent window.

Summary: Currently, the `AphlictClient` will only send its subscriptions to the `AphlictMaster` once. If the original `AphlictMaster` is closed and a new master is created, then client subscriptions will be lost.
Test Plan: Opened two separate tabs. Closed the "master" tab and noticed that the subscriptions were re-sent to the server.

Summary: Ref T4324. Ref T5284. This adds server-side support for keeping track of a set of PHIDs that the Aphlict clients have subscribed to. Instead of broadcasting a notification to all clients (after which the clients can poll `/notification/individual` in order to determine whether or not they are interested in the notification), transmit notifications only to clients that have subscribed to a PHID that is relevant to the notification.
Test Plan:
I opened up two clients on the same host (incognito tabs in Chrome). Here is the output from the server:
```

I verified (using the "Network" tab in Chrome) that an AJAX request to `/notification/individual/` was only made in the tab belonging to the user that triggered the test notification.

Summary: Currently, any error thrown when instantiating an `AphlictMaster` will be assumed to be due to the master already existing. This is a bit overzealous because the [[http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/LocalConnection.html#connect() | documentation]] specifically states than an `ArgumentError` will be throw if "the `LocalConnection` instance is already connected".
Test Plan: Inspected the log message.

Summary:
Ref T4324. Currently, an Aphlict client (with a corresponding connection to the Aphlict Server) is created for every tab that a user has open. This significantly affects the scalability of Aphlict as a service. Instead, we can use `LocalConnection` instances to coordinate the communication of multiple Aphlict clients to the server.
Similar functionality existed prior to D2704, but was removed as the author was not able to get this functionality working as intended. It seems that the main issue with the initial attempt was the use of the `setTimeout` function, which seemed to be a blocking call which prevented messages from being received. I have instead used an event-based model using a `Timer` object.
Roughly this works as follows:
# The first instance will create an `AphlictClient` and an `AphlictMaster`. The `AphlictClient` will register itself with the `AphlictMaster` and will consequently be notified of incoming messages.
# The `AphlictClient` is then responsible for pinging the `AphlictMaster` at regular intervals. If the client does not ping the master in a given period of time, the master will assume that the client is dead and will remove the client from the pool.
# Similarly, the `AphlictMaster` is required to respond to pings with a "pong" response. The pong response lets the clients know that the `AphlictMaster` is still alive. If the clients do not receive a pong in a given period of time, then the clients will attempt to spawn a new master.
Test Plan: I have tested this on our Phabricator install with a few tabs opened and inspecting the console output. I will upload a screencast of my test results.
