cellar db population script

Hey,

Your README says:

``` bash
mysql cellar -u root < cellar.sql
```

But I believe it should be:

``` bash
mysql cellar -u root -p < cellar.sql
```

At least, this is what I needed to do with a fresh install on Ubuntu 12.04 with mysql-server: Server version: 5.5.24-0ubuntu0.12.04.1 (Ubuntu)

Cheers,
Stefano
