Closes: #2343

Protoc was updated a little while ago and we are likely to get more
people using it. This should avoid weird merge conflicts and bump us
to the latest version

Added a note that helm needs to be in a
specific directory path in order for it
to be compiled.

This adds a hidden 'helm doc' command that generates documentation out
of the Helm help text.

Currently it can create:

- man pages for HELM(1)
- Markdown documentation
- bash autocompletions

Those are the three built-ins for Cobra.

The command is hidden so that it doesn't show up to the regular user,
since this is really a specialized task. It has the advantage of making
it trivially easy to install man pages and bash completion at installation time.

This refreshes docs, as discussed in #719, and adds a few new sections
to the docs.

Closes #719
