feat(helm): support command-line values for install

fix(tiller): improve deletion error messages

feat(ci): validate license block in source files

Add support for specifying key/value pairs on the command line, instead
of only in a YAML file.

This currently accepts either command line pairs or a YAML file, but
does not support combining the two.

Closes #944

feat(ci): run test coverage in parallel

This stops a repeat deletion from sending requests all the way to
Kubernetes, and gives a clear error message when a deletion is requested
on an already deleted resource.

Relates to #972

```
./scripts/coverage.sh  37.25s user 4.15s system 144% cpu 28.615 total
```
```
./scripts/coverage.sh  47.96s user 6.77s system 567% cpu 9.647 total
```

fix(tiller): provide filename when YAML is bad

feat(helm): add 'helm inspect'

This makes the template system less tolerant in the name of detecting
YAML parse errors before things are sent to Kubernetes. It returns a
more detailed error message when a template creates a manifest which is
not valid YAML.

Closes #957

This basic version of helm inspect displays the Chart.yaml and
values.yaml files on STDOUT.

Closes #967

docs(README): update README with basic information

The README reflected an earlier stage of project development. This
update gives more useful "Why Helm?" documentation at the top, and
updates several of the instructions to be more reflective of current
status.

docs(charts): explain hook resource lifecycle

feat(*): install releases into namespace

docs(logo): add the official helm logo png

chore(ci): bump go to v1.6.3

This explains how a hook resource is not managed as part of the release
lifecycle.

Closes #960

feat(helm): add --no-hook to helm install and delete

This also adds several tests, cleanups to the API, and removal of dead
code.

Relates to #932

docs(charts): add documentation for hooks.

Fix #872: index function should handle deleted charts correctly

feat(build): add make target for cross builds

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.

ref(cmd): refactor status cmd

Add reference to text/template Go package doc

Closes #938
