Fix repo prefix searchbug

fix(manager): add test for getDeployments*

feat(deployment): add describe command to helm cli

fix(validate-go): show the errors gofmt found

Repo name routes, tests and cleanups

Factor expansion service logic as an auxiliary library

fix(manager): add test for listDeploymentsRequestHandler

Rather than just listing files that have errors, this now shows
the diff of what gofmt things should be the case, and what is
the case.

doc(cli): improve help output

feat(glide.yaml): Add versions to dependencies

Additionally:
- corrected the appengine import name
- Added the license field

fix(cli): change deployment delete to remove

feat(repo): remove repo by name + refactors

This is for consistency. Other commands use 'remove,rm' as removal
verbs. Example: 'helm repo rm'

feat(cli): move 'helm dm' to 'helm server'

fix(*): fix license headers

doc(workflow): fix references to 'dm' commands

* + fix old repo tests for Name addition

doc(chart_format): fix title and intro

This is no longer a proposal, so the intro now reflects that.
