feat(ci): upload checksum with binary releases

closes #1214

fix(helm): resolve URLs and SemVers correctly

docs(spelling): Fix some random misspellings

The original dependency resolution did not correctly resolve version or
URL of a dependency. Version was tracked by filename, and URL was
assumed to be absolute. This fixes both of those.

Closes #1277

feat(helm): add --versions flag on search

fix(*): remove references to gopkg.in/yaml.v2

fix(index): Append just the filename instead of full path to the url

fix(cmd/hist): print revision history with unix synergy

fix(1246): pull most recent release from history

feat(helm/cmd): support for retrieving release history

This removes the last of the requests for gopkg.in/yaml.v2, and
also the struct annotations.

Closes #1192
Closes #1263

This causes search to index by name/version instead of just name, which
means you can get a list of versions of a chart. The '--versions' flag
enables this behavior.

Partially fixes #1199

fix(repo): auto-update index file formats

fix(helm): fix 'helm search' to use UITable

This performs a relatively weak in-memory translation of index file
data. It does not, in most cases, write the corrected data to disk, and
it emits a warning directly to STDERR each time it loads a deprecated
index.

Known limitations:

- It cannot recover certain bogus records that earlier alpha releases
  generated (notably, where all chartfile data is missing)
- In some cases, it has to parse a filename to get version info. This is
  lossy.
- Because it takes three passes through the YAML and JSON unmarshal, it
  is not performant.

This feature is transitional and should be removed during the Beta
cycle, prior to the release of 2.0.0.

Closes #1265

feat(tiller): re-use values during upgrade

When `helm install -f foo.yaml bar` is called, and then the release is
upgraded with `helm upgrade happy-panda bar`, this will now re-use the
values that were submitted with `-f foo.yaml`. The same is true for
values specified with `--set`.

Closes #1227

Closes #1261

docs(using_helm): change reference from npm to CPAN/Fedora DB

Closes #1271

docs(install): Add information on using canary releases

fix(helm): fix tests so that they do not write data into testdata

chore(helm): add test coverage to pkg/helm

This includes documentation on how to use Helm and Tiller canary
releases.

There was a bug in the repo tests that caused them to overwrite the
repositories.yaml file in that directory. Now, the entire tests (server
and client-side) run inside of a temp directory.

fix(chart): Chart.yaml now has an apiVersion field.

feat(helm): implement new index format

This implements a new index file format for repository indices. It also
implements a new format for requirements.yaml.

Breaking change: This will break all previous versions of Helm, and will
impact helm search, repo, serve, and fetch functions.

Closes #1197

fix(helm): change 'helm update' to 'helm repo update'

chore(ci): go1.7.1

The old form is marked deprecated.

Relates to #1196
