fix(helm): add no-hooks to upgrade

Mark disable-hooks as deprecated.

Closes #1575

fix(helm): pass the no-hooks flag during upgrade

fix(helm): improve URL comparison logic

fix(Makefile): build windows amd64 binaries

fix(helm): fix doc string for ErrNotList

fix(tiller): validate names before performing operations

Normalize URLs before comparing them. This deviates slightly from the
URL spec, but in order to accomodate the predominant use pattern for
Helm. Specifically, './', '../', and '/' are all "interpreted" to be
filepath-like.

Closes #1588

This adds back support for Windows now that it has been tested by the
community.

Closes #1596

This just moves a var declaration to the top of a file and then properly
documents it.

Remove double explanation of why MariaDB is in the list

Helm upgrades were not passing the no-hooks value to the server.

Closes #1590

feat(helm): add command to generate documentation

feat(helm): add plugin system backend

This adds a hidden 'helm doc' command that generates documentation out
of the Helm help text.

Currently it can create:

- man pages for HELM(1)
- Markdown documentation
- bash autocompletions

Those are the three built-ins for Cobra.

The command is hidden so that it doesn't show up to the regular user,
since this is really a specialized task. It has the advantage of making
it trivially easy to install man pages and bash completion at installation time.

Add a checksum function to the template engine

fix(semver): range handling includes prerelease when it should not

fix(helm): improve --set parser

fix(helm): fix windows support with port forward connection in setupConnection

There were several places where an invalid name could be interpreted
into a wild-card by Kubernetes. That allows Bad Things.

This fix requires names to match the Kubernetes pattern for naming.

Closes #1594

This fixes the port forward connection using helm on windows by assigning explicitely 'localhost' to 'TillerHost' in 'setupConnection'. Otherwise, the connection between the helm client with the Tiller server deployed on Kubernetes will not work.

This adds a backend for a plugin system.

Closes #1572

A bug in the semver package caused prereleases to be included in
version ranges by default. Prereleases, per the spec, are not
expected to be API compatible with the releases themselves.

The semver package now ignores prereleases when evaluating
constraints when the constraint does not contain a prerelease. If
the constraint contains a prerelease they are evaluated.

chore(*): remove glide hacks that are no longer required

This replaces the old set parser with a brand new one. This also changes
the internal algorithm from duplicating YAML to merging YAML, which
might solve a problem one user reported in chat, but which was never
captured in an issue.

Closes #1540
Closes #1556

feat(helm): support 'helm create --starter=mypack'

This adds support for packs, pre-configured chart patterns that can be
used to quickly create a custom layout for your new chart.

fix(helm): don't pass nil-opt to ReleaseContent

feat(kube): add schema validation

Adds validation against the swagger schema.

Example error:
Error: release telling-wildebeest failed: error validating "": error
validating data: expected type int, for field
spec.template.spec.containers[0].ports[0].containerPort, got string

Current error:
unable to decode "": [pos 177]: json: expect char '"' but got char 'n'"'

fix(requirements): accept semver constraints for the versions in the requirements.yaml

fix(tiller): allow release name to be up to 53 chars

fix(kube): fix incomplete patches generated on update
