Adding leave and change-owner to organizations

[eporama]

I also changed the comment to use the consistent American spelling of organization since all of the methods and classes use that…

Not sure what tests need to be added as methods such as deleteMember don't seem to be tested either.

Also, the $options is marked as json assuming that #82 is merged… otherwise we should revert it to form_params

I’ve generally tried to keep the API calling methods of this library 100% tested so we don’t fall behind on testing as new methods are added. What has happened though is that as the library has grown, I’ve noticed that the tests probably aren’t in the most optimal places within the repo.

Not sure why it's still down, I added tests for the two methods… but .003% ? Maybe I need to add some tests for the Connector as well? ;-)
