Title: The sed command requires an argument for the -i parameter on Mac OSX even if the argument is an empty string. This argument is not required on Linux.

I was trying to build the create library on a Mac and I kept running into this error

```
Executing sed -i 's/{{ VERSION }}/1.0.0alpha4/' /Users/jbeach/code/bergie/create/examples/create.js
{ [Error: Command failed: sed: 1: "/Users/jbeach/code/berg ...": invalid command code j
] killed: false, code: 1, signal: null }
sed: 1: "/Users/jbeach/code/berg ...": invalid command code j
```

A little googling lead me to this note on stackoverflow about the sed command requiring an argument to the -i parameter on Mac, but not Linux.

Hopefully this patch will run on Linux as well. I can't test it locally not having a Linux install.
