This adds code to parse TOML files into Values maps. These can then
easily be passed into the template engine.

Included in this is support for TOML "tables", subsections of TOML
files. We will be using those to pass config data to dependent charts.

fix(Makefile): disable verbose on build

feat(chart): add chart package

feat(storage): add basic implementation of storage

feat(init): add helm init

+ -i flag to override tiller image

This is the chart package from k8s/helm, modified for usage here.

This adds a higher level set of tests for storage.

feat(Makefile): add docker build tooling

This is an in-memory storage layer for storing releases. This will be
superseded by the Kubernetes ConfigMap implementtion.

Still needs a dockerfile

fix(environment): make KubeClient take multiple files

fix(tiller): set up Tiller environment correctly

Rather than just taking a []byte for Install, take a map of
filenames->contents.

And structure the tests better.

feat(engine): add template engine

fix(scripts): go vet is built into go

feat(Makefile): add Makefile

fix(environment): add tests for Environment

feat(proto): stub out a Chartfile message

feat(proto): first protos for helm

feat(helm): add initial helm client
