faraday was throwing "cant load such file hashie/mashify" upon Camlistore.new

Upon calling Camlistore.new , faraday was blowing up with 

```
:: be rails c
Loading development environment (Rails 4.0.0)
irb(main):001:0> camli = Camlistore.new
RuntimeError: missing dependency for FaradayMiddleware::Mashify: cannot load such file -- hashie/mash
```

Adding hashie as a runtime dependency fixed this for me. Please verify as maybe this is a local issue.
