Michael Bridgen 2bb09697ce Centralise adapter types
Since the generic commands tend to share a few of the methods they
need -- at least AsClientObject -- it's worth having just one wrapper
struct for each API type, and adding methods to it where necessary.

For the automation types, I put these in auto.go.

While doing this I also did some tidying:

 - I changed the name of the wrappers to `<type>Adapter`, and the
   generic adapter to `universalAdapter` (it's only needed for delete,
   so far).

 - I de-exported and renamed some interface methods e.g.,
   `exportItem`. They aren't needed outside the package.
