This adds support for the following 'helm list' flags:

- all: show all release types
- deleted: show deleted releases
- deployed: show deployed releases
- failed: show failed releases

These flags can be toggled. Only '--deployed' is turned on by default.

On the server side, Tiller's list function can now filter based on a
slice of release.Status_Code filters. While the client only supports a
subset, the server supports all known release.Status_Code types.

Closes #973

This will allow helm install to re-use names for releases that were
already deleted.

This includes a substantial bit of unit test improvements. Also, in
order to allow us to tests command line args (which translate to
helm.Option objects), I had to add a new interface to pkg/helm.

This makes it possible for the user to specify their own release name
instead of accepting the generated one.

Also noticed a field was omitted from metadata.proto and the docs.
Added it back, though functionally it is a no-op.

Previously, paging used the last release name of the current set to ask
for more results. Now switched to using the first name of the next set.

Not sure I like this method. It makes the user experience more
complicated.

This adds support for filtering list results. Filter strings are
passed from Helm to Tiller, where they are compiled as regular
expressions and executed against the list of releases. Only matching
releases are returned.

Filters are applied before limits and sorts.

This fixes indentation, documentation, and removes unused protobuf
files.

This adds support for dry run on install, as well as providing
enough info for an install to display (verbose) manifests. While
doing this, I ended up just storing the rendered manifests for
simplicity.

	1. remove preliminary hapi protocol buffer definitions
	2. modify hapi Makefile
	3. update hapi protobuf model in _proto/hapi/{chart,release,services}
	4. generate protobuf src to pkg/proto/hapi/{chart,release,services}
