Previous versions of Helm had placeholder text in the index.yaml file.
This generates an HTML index for 'helm serve'. It also has a
refactoring of the server so that the server can be tested.

Closes #1397

fix(helm): make 'helm repo index' generate the right index

This prevents the index command from recursing through directories.
Behind the scenes, it swaps out the repository logic for the index file
logic.

Closes #1328

fix(1357): print help text if revision is not specified

feat(helm): `--no-update` flag for `helm repo add`

fix(helm): show failed releases by default

doc(rollback): add docs for pre/post rollback hooks

docs(provenance): describe signature authority

fix(tiller): fix wording for a few errors

fix(tiller): fix nil pointers in error messages

This changes the wording of a log and an error message to make it
clearer what is happening.

There were a few places where error messages were accessing properties
of objects that were nil because of the error.

Closes #1374

For 'helm list', this now shows both deployed and failed releases by
default.

Closes #1387

fix(kube): find current resource by name and kind

fix(*): statically link cross builds

fix(helm): return correct version on dep up

docs(*): refresh docs

closes: #1362

fix(1333): cannot delete release in failed state

There was an extra return statement in a helper that was causing
the download manager to get a false positive on a release version.

Closes #1383

This resolves #1210. Update will find current resource
by name and kind for comparison purposes.

This refreshes docs, as discussed in #719, and adds a few new sections
to the docs.

Closes #719

Fix/tiller helm flags

docs(helm): Fix broken link to glide project

fix(linter): add engine.FuncMap so linter can use real function list

chore(docs): fix nginx example templates

Closes #1072

This adds a function engine.FuncMap that returns a function mapping that
better represents the functions passed to a template. The linting logic
is reconfigured to use this function instead of the sprig.FuncMap
function.

Closes #1366

fix(lint): validateNoMissingValues template regex

fix(lint): use correct hash key for rendered tmpl

fix(helm): make 'helm install' output more consistent
