Change fake and refactor app_bits repo. - App bits repo is much more tightly scoped
The App Bits repo has a counterfeiter fake, and lives in its own
package

We now have a push actor
Former responsibilities of the App Bits repo have been divided between
the App Bits repo, the push command, and the push actor.
All this should make the future implementation of an "upload bits"
command much easier/possible.
