ref(plugin): cleanup unused functions

Replaced InstallRelease with InstallReleaseFromChart in cmd/install.go

Fixes https://github.com/kubernetes/helm/issues/2240

`helm install` command was calling chartutil.Load twice,
once from `run` method and
another time from `client.InstallRelease` which is called from `run` method in `cmd/helm/install.go`

Closes #2238

docs(*): Adds developer workflow documentation

This adds documentation for the developer workflow as approved in #2069

Closes #2069

This provides the Chart.yaml field `tillerVersion`, which is a semver
range. It allows users to choose to constrain a chart to a specific
version.

The reason for this is that we keep introducing new template functions,
but we have no way of saying "this chart will only work with Tiller
newer than...".

The check on version is _only_ done on Tiller. The client does not check
at all, since it does not do any template expansion on its own.

docs(plugins): add app registry plugin link

feat(helm): add plugin management commands

Add plugin management subcommands for installing and removing plugins

Install accepts a vcs url or a local directory.

$ helm plugin install http://github.com/adamreese/helm-env
Installed plugin: env

$ helm plugin list
NAME    	VERSION	DESCRIPTION
env     	0.1.0  	Print out the helm environment.

$ helm plugin remove env
Removed plugin: env
```
