remove org permission preview media type

These changes are now official, so the custom media type is no longer
needed.  This does go ahead and remove RepositoryListOptions.IncludeOrg
which was being used to trigger the custom media type.  Even though this
is a breaking change, it was only in for a month and I don't think it
was too widely used during that time.

Fixes #219
