Merge pull request #2 from fogeytron/master

Add Ability to download raw media files.

Thanks for this!  Typically we would look for pull requests that do not include multiple tickets (registration misspelling as well as the changes from the limits branch).  In this case since they are all planned to be merged in anyway we can accept it all at once.  However, in the future each of these issues should be separate pull requests.

I also apologize for the time it took to review this.  We do not have an engineer currently assigned to work on the SDK so this repo is not being checked on a regular schedule.  I will try to make sure I check it at least once a week moving forward.
