fixes cloudfront config bug

* Cloudfront dist url is now expected at $config['cloudFrontUrl']
    rather than $config['adapterOptions'][2]. The old var broke adapters
    because $config['adapterOptions'] is passed directly to the
    adapter constructor.

* Fixed spelling error in function name: clould to cloud
Merge pull request #30 from clawsonm/cloudfront-breaks-adapter-options
