ref(chartutil): move chart loading out of chartutil into new package
    add chart loader interface to allow lazy loading
feat(chart): create chart accessors
ref(*): cleanup requirements
ref(tiller): remove optional template engines
ref(tiller): simplify sorting releases and hooks
ref(*): code simplification
ref(hapi): move chart package out of hapi
ref(chart): add requirements and lock to Chart struct

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

This also removes the last of the TOML code.

Closes #822

As a carryover from the days when we only allowed one source, the source
field was still labeled 'source' instead of 'sources'. Fixed and updated
all of the tests.

  1. install command loads chart archive.
  2. invokes helm api to transform the pkg/chart.Chart type
     to it's proto model.
  3. the client then establishes a connection to tiller.
  4. sends InstallReleaseRequest, receives InstallReleaseResponse.

todo (for complete install):
  - walk pkg/chart.{Values,Deps,Templates} types and populate proto
    definitions for various apis/messages.

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.

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

chartify create deployment API
modify CLI to match

* since it's not being used outside of this package
* also LoadContent -> loadContent for same reason
* This addresses some style issues from #401

* Fixes some style errors in #401
