Most commands use either a kind, or a more readable spelling of a
kind, in their output. To make this easier, this centralises the
definition of those names in one place, and lets the command
implementations choose whichever they need.

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.
