Fixes for external stack deployment (#851)

Fixes
- stack path resolution for `build`
- external stack path resolution for deployments
- "extra" config detection
- `deployment ports` command
- `version` command in dist or source install (without build_tag.txt)
- `setup-repos`, so it won't die when an existing repo is not at a branch or exact tag
