deploy: deploy local directory and run it in place

* Expects:
  - POST {local-directory: ...}
  - Content Type: application/x-pm-deploy
* Skips build/prepare steps
* Does not symlink the current directory
Is this necessary? I don't see it being set to false for the git receive path, so its confuses me that its here. If its necessary, it should be in both tarball and git paths, if its not necessary it should be in neither. I suspect that as undefined properties are falsy, its not necessary.
