Title: Fix Rackspace getFiles Parameters

Rackspace returns different details with underscore, not with minus
`content_type` `content-type`

Example at issue https://github.com/nodejitsu/pkgcloud/issues/105

I dont now if this was a change in rackspace api (use it since a short time), so i leave `content-type` and the other changed fields as fallback in code.
