If a release's v1 config map was removed, 'helm upgrade' would fail. It
was calling the wrong function to get its history. This has been fixed.

Closes #1829

Headless services (with `clusterIP` set to `None`) were reporting
as not being ready because they didn't have an IP address. This adds
a logic check to ignore those services.

If a selector is created from invalid values it will return nil.

Which is EVERYTHING!!!

When manifests do not change, they didn't get populated with the
latest label info from the API server and then panic'd. This resolves
that bug

docs(related): Add link to croc-hunter video

When 'helm install', 'helm package', and 'helm upgrade' are run,

in charts/.
