Title: Shell cleanups

These were mostly obvious to me after quickly taking a glance at the code. Nice script, very clever :)

The lines like this:
```bash
GRAPHITE_SERVER=${GRAPHITE_SERVER:=localhost}
```

Allow you to do something akin to:
```bash
GRAPHITE_SERVER=carbon.host ./pipe-to-graphite.sh ...
```
