Summary: Fixes T5126. Provide `start`, `stop`, `restart`, `debug` and `status` workflows for `./bin/aphlict`. This makes it easier to manage Aphlict as if it were a service.
Test Plan:
```
> sudo ./bin/aphlict status
Aphlict is not running.
> sudo ./bin/aphlict stop
Aphlict is not running.
> sudo ./bin/aphlict start
Aphlict Server started.
> sudo ./bin/aphlict status
Aphlict (12880) is running.
> sudo ./bin/aphlict restart
Stopping Aphlict Server (12880)...
Aphlict Server (12880) exited normally.
Aphlict Server started.
> sudo ./bin/aphlict stop
Stopping Aphlict Server (12895)...
Aphlict Server (12895) exited normally.
> sudo ./bin/aphlict debug
Starting Aphlict server in foreground...
Launching server:
$ node '/usr/src/phabricator/src/applications/aphlict/management/../../../../support/aphlict/server/aphlict_server.js' --port='22280' --admin='22281' --host='localhost' --user='aphlict'
[Fri May 30 2014 09:56:14 GMT+0000 (UTC)] Started Server (PID 12911)
