fix(proto): keep a local protoc Go plugin

This works around issues where $GOPATH/bin has a different version of
the protobuf Go plugin than the one Kubernetes uses.

fix(issue/841): capitalization and punctuation consistency.

Sorting Wildcard function

feat(helm): add 'helm get values --all' for all values

Add support for displaying computed configuration values. This is
useful for debugging.

Templates partials

fix(pkg/chart): remove pkg/chart

This is the final step in replacing pkg/chart with pkg/chartutil.

This also removes the last of the TOML code.

feat(pkg/ignore): add helmignore library

ref(pkg/helm) replace  'pkg/helm' with 'pkg/helmx'

includes:
 - (#826) removal old pkg/helm

ref(pkg/helm): package helm refactor

includes:
 - (#828) helm client grpc support ported from old pkg/helm
 - comment consistencey & style fix
 - gofmt pkg/helmx

This adds support for .helmignore files. These files roughly follow
the conventions established for .gitignore files:
https://git-scm.com/docs/gitignore

Closes #748

feat(chartutil): support global variables

fix(helm): fix two panics in 'helm search'

fix(tiller): allow different template engine

fix(helm): add 'helm repo rm' alias

ref(pkg/helm): package helm refactor

This is a minor fix to the Tiller internals to allow an alternate
template engine. This will still require future work to make it possible
to bootstrap in a different template renderer.

includes:
 - (#825) comptability interface between
          old/pkg/helm and new/pkg/helm

 - (#827) helm client scaffolding and
          rpc / release options

fix(helm): read values.yaml instead of values.toml

Closes #822

This provides support for "global" variables. It does this by
declaring "global" to be a special namespace. It then copies this
namespace into every subchart, coalescing it into any "global"
namespace found there.

The net result is that if "global.foo" is set in the YAML file, it
will be available to every chart/subchart as ".global.foo" regardless of
where that chart is in the subchart tree.

fix(helm): s/arbitary/arbitrary/

fix(chartutil): move values coalescing into chartutil

docs(*): fix links

fix(helm): add .tgz to package names on fetch

fix(helm): produce error if package name is inconsistent

'helm package' now produces an error if the directory name and the name
in Chart.yaml are not the same.

Closes #812

Closes #809
