Version 0.9 Released
- Added the 'modifyResponse()' method into the \Embera\Adapters\Service.
  This method gives the hability to modify the fake-response/oembed-response
  from a oembed service provider.
  With this method I can generate missing keys - For example some services
  don't provide an 'html' key. With this method I can generate it based on
  the original response and on a per service basis.
- I'm tagging the library as version 0.9. The library is stable enough
  and I'm happy with the current API, so I'm not going to add more changes
  to the core.
  Before releasing version 1.0, I'm going to focus on:
    - More Testing.
    - Adding offline support to more services.
    - Adding 'html' keys to services that don't provide it on their response.
