Closes #1744

There was a hyphen range bug in semver that prevented constraints
in the form of v2.3.5-20161202202307-sha.e8fc5e5. This would be
parsed incorrectly as a hyphen range and then fail. The bug in
semver was fixed in semver v1.2.2 for this issue.

This adds shasum, int, and float64 functions, and fixes quote escaping
for 'quote'.

Closes #1524

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.

- decouple tunnel from kube client
- add context switching for init cmd
- add unit tests for installer and init command
- refactor installer and remove unused code

This removes the last of the requests for gopkg.in/yaml.v2, and
also the struct annotations.

Closes #1192
Closes #1263

This starts with #1211 and does the other updates necessary for
bumping us to Kubernetes 1.4.

This adds support for OpenPGP signatures containing provenance data.
Such information can be used to verify the integrity of a Chart by
testing that its file hash, metadata, and images are correct.

This first PR does not contain all of the tooling necessary for
end-to-end chart integrity. It contains just the library.

See #983

We need this specifically for trimSuffix.

Closes #1055

Looks like another Go git repo got moved around.

* Thanks for the reminder adam :)

New template functions like trunc will be really helpful for dealing
with Kubernetes naming limits.

This is the final step in replacing pkg/chart with pkg/chartutil.

This also removes the last of the TOML code.

Also updated the lock file as part of this, and there are a lot of
changes there.

details: the host flag for install overrides the
TILLER_HOST env var. If neither are set,
host defaults to ":44134".
