feat(charts): add 'dependencies:' to Chart.yaml

fix(tiller): store failed release on post-inst failure

feat(release): remove tiller from cross compile

fix(kube): delete should skip resources not found

This feature adds a dependencies section to a chart file. It is a
prerequisite for adding automated chart management tooling as described
in #874.

fix(helm): removed debug output

This fixes a bug where post-install hooks did not result in recording a
failure.

Also fixed a bug where a `--dry-run` will result in an error because
of the recently added status support.

There are several other output inconsistencies that I noticed and filed
as issue #1135.

Closes #1130

fix(tiller): Install --replace will result in an upgrade

If a release has been deleted, `install --replace` will work but the release
status will still be "deleted". This means that subsequest attempts to
change the release will fail. Upgrading the release instead will prevent
such zombie releases.

Closes #1131

feat(rollback-support): add version field to protos

chore(tiller): delete redundant testing of storage in pkg/environment

fix(tiller): return status for deleted release

This modifies `helm status` to return info about deleted and failed
releases. We do our best to retrieve info for releases that were
partially deployed.
