New command line action: importBundle; load bootstrap bundle on first run

- importBundle imports zip archive of sites
- latest bootstrapping bundle is downloaded if data/ dir is empty; primary
  reason for this for now is to avoid constantly updating tracker list in
  git tree and use Syncronite instead
