776a240870 Let Aphlict listen on the specified host
Summary: We allow user to specify the host to listen to but we listen on 127.0.0.1 instead.

Test Plan:
Hardcoded the path and verified that I can connect to the host from other machine.

Verified that `localhost` still doesn't allow remote connections.

86040227b0 Improve Aphlict server
Summary:
  - Move to port 22280 by default.
  - Warn when running as non-root.
  - Allow subscription and publish/admin ports to be configured.
  - Allow server to drop root after binding to 843.
  - Allow log path to be configured.
  - Add /status/ admin URI which shows server status.
  - Return HTTP 400 Bad Request for other requests, instead of hanging.
  - Minor formatting cleanup.

Test Plan:
Ran without root:

  $ node aphlict_server.js

...got a good error message. Ran with --user:

  $ sudo node aphlict_server.js --user=epriestley

...verified server dropped permissions. Ran with --port / --admin. Hit /status/ with GET, got status. Hit other URLs with GET, got 400.

f8f195b329 Make Notifications Realtime
Summary:
Adds the node.js Aphlict server, the flash Aphlict client, and some
supporting javascript. Built on top of - and requires - D2703 (which is still
in progress).  Will likely work with no modification on top of the final
version, though.

The node server is currently run with

   sudo node support/aphlict/server/aphlict_server.js

Test Plan: tested locally

f8431bbfee Make Aphlict client somewhat more approachable
Summary: Provide a reasonable JS API for the Aphlict client. Provide an example behavior to invoke it.

Test Plan:
Ran "aphlict_server.js" with:

  $ sudo node aphlict_server.js

Loaded /aphlict/. Opened console. Got "hello" from the server every second.

Got reasonable errors with the server not present ("Security exception", but this is because it can't connect to port 843 to access the policy server).

84731e8f00 Aphlict, simple notification server
Summary:
This is purely a prototype at the moment, but the basic functionality sort of
works.

I'm not sure how far I want to go with this but I think we might be able to get
somewhere without it being gross.

The idea here is to build a notification server WITHOUT using Comet, since Comet
is extremely difficult and complicated.

Instead, I use Flash on the client. LocalConnection allows flash instances to
talk to each other and connect() can be used as a locking primitive. This allows
all the instances to elect a master instance in a race-safe way. The master is
responsible for opening a single connnection to the server.

On the server, I use Node.js since PHP is pretty unsuitable for this task.

See Github Issue #3: https://github.com/facebook/phabricator/issues/3

One thing I need to figure out next is if I can reasonably do SSL/TSL over Flash
(it looks like I can, in theory, with the as3crypto library) or if the server
needs to just send down version information and trigger a separate Ajax call on
the client.

Test Plan:
Created a client pool and connected it to the server, with election and failover
apparently working correctly.
