feat(pkg): add a timeconv.String function

Rather than do the same formatting repeatedly, we can just call a
convenience function to format to a specific format.

Fix(readme): Add more documentation on getting started.

fix(helm): make install ouput similar to others

feat(helm): add helm update command

fix(helm): improve 'helm get' output

This makes the output of 'helm get' more like the output of other
Helm commands.

This now uses the global verbose flag (instead of a local one) and
formats the output in roughly the same style that 'helm list' and
'helm repo *' use.

feat(tiller): allow specifying namespace on cli

Add client-only flag to helm init that skips installing tiller.

Add search support

Fix bootstrap instructions

The command is `make bootstrap build` not `make boostrap build`.

fix(Makefile): fix broken cross binary build

feat(tiller): delete operation runs against Kubernetes

Add ability to untar charts after downloading them

fix(Makefile): add bootstrap warnings

fix(local-cluster): check to see if kubelet is running

See #647

Also fixed a minor formatting issue with Alpine chart in docs.

feat(kube): add delete method

* Fixing the make target in the readme (misspelling)
* Adding link to Glide.

feat(helm, tiller): implement k8s portion of install

Add support for fetching full urls.
