Sam Saffron fb8d1f35a4 DEV: support USR2 to restart unicorn in dev mode
In dev mode sending USR2 to the unicorn master supervisor process will
restart unicorn.

This allows a simple script like this to restart unicorn in dev:

```
#!/usr/bin/env bash

kill -s USR2 `ps aux | grep ruby\ bin\/unicorn | grep -v grep | awk '{print $2}'`
```
