Treat ClipAppArgs independently of ClipApp

You might conceivably want to set one without setting the other. For
example, on OS X, you might want to keep `pbcopy`, but instead use
`-pboard find` (for some crazy reason).

This isn't exposed as a command-line flag right now, so the only way you
could do such a thing would be to provide a custom JSON config file.
