53834d1471 Enable "strict" mode for NodeJS
Summary:
In particular, this changes the behavior of NodeJS in the following ways:

- Any attempt to get or modify the global object will result in an error.
- `null` values of `this` will no longer be evaluated to the global object and primitive values of this will not be converted to wrapper objects.
- Writing or deleting properties which have there writeable or configurable attributes set to false will now throw an error instead of failing silently.
- Adding a property to an object whose extensible attribute is false will also throw an error now.
- A functions arguments are not writeable so attempting to change them will now throw an error `arguments = [...]`.
- `with(){}` statements are gone.
- Use of `eval` is effectively banned.
- `eval` and `arguments` are not allowed as variable or function identifiers in any scope.
- The identifiers `implements`, `interface`, `let`, `package`, `private`, `protected`, `public`, `static` and `yield` are all now reserved for future use (roll on ES6).

Test Plan: Verified that Aphlict was still functional.

4636833f3d Fix module imports in Aphlict server
Summary:
This was broken in D11383. Basically, I had the `ws` module installed globally whilst testing, but the changes made do not work if the `ws` module is installed locally (i.e. in the `./support/aphlict/server/node_modules` directory). After poking around, it seems that this is due to the sandboxing that is done by `JX.require`.

A quick fix is to just //not// use `JX.require`, although you may have a better idea?

The error that is occurring is as follows:

```
<<< UNCAUGHT EXCEPTION! >>>

Error: Cannot find module 'ws'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)

    at Module._compile (module.js:456:26)
>>> Server exited!
```

Test Plan: Now able to start the Aphlict server.

9a7ad972cd Refactoring of the Aphlict server
Summary: Tidy the Aphlict server by splitting the functionality into two main modules, `AphlictClientServer` and `AphlictAdminServer. There is still further tidying that could be done here, but I feel that this puts us in a much better place.

Test Plan: Sent notifications via `/notification/status/`.

270a0c54b4 Fix permissions on Aphlict log
Summary: Currently, the Aphlict server created the log file (if it doesn't exist) but then immediately fails with "Unable to open logfile". It seems that we don't set the permissions correctly.

Test Plan: Deleted log file and was able to start the Aphlict server.

0d070c91dc Fix Aphlict logging
Summary:
Yeahhhhhhhh....

  - Open a "stream", not a "steam".
  - Make error easier for users to understand.
  - Write to the log in debug mode so the issue is more apparent.

Test Plan:
  - Started server with bad permissions, got usable error message.
  - Started server with good permissions, got logfile.

ab4324148a Make the Aphlict server more resilient.
Summary:
Currently, the Aphlict server will crash if invalid JSON data is `POST`ed to it. I have fixed this to, instead, return a 400. Also made some minor formatting changes.

Ref T4324. Ref T5284. Also, modify the data structure that is passed around (i.e. `POST`ed to the Aphlict server and broadcast to the Aphlict clients) to include the subscribers. Initially, I figured that we shouldn't expose this information to the clients... however, it is necessary for T4324 that the `AphlictMaster` is able to route a notification to the appropriate clients.

Test Plan:
Making the following `curl` request: `curl --data "{" http://localhost:22281/`.

**Before**
```
sudo ./bin/aphlict debug
Starting Aphlict server in foreground...
Launching server:

    $ 'nodejs' '/usr/src/phabricator/src/applications/aphlict/management/../../../../support/aphlict/server/aphlict_server.js' --port='22280' --admin='22281' --host='localhost' --user='aphlict'

[Wed Jun 11 2014 17:07:51 GMT+0000 (UTC)] Started Server (PID 2033)
[Wed Jun 11 2014 17:07:55 GMT+0000 (UTC)]
<<< UNCAUGHT EXCEPTION! >>>

SyntaxError: Unexpected end of input
>>> Server exited!
```

**After**
(No output... the bad JSON is caught and a 400 is returned)

28fe44da0a Break some of Aphlict into reasonable classes with sensible responsibilities
Summary:
Ref T4324.

  - Create `Listener` to represent listening clients.
  - Create `ListenerList` to represent the current list of clients.
  - Create `Logfile` to handle logging.

Test Plan: Clicked "Send Test Notification", verified logs, status and notifications all work correctly.
