nit: fix spelling of dependency

fix change requests

The following commands:
helm dep update
helm dep build
are now able to take a requirements.yaml with dependency charts' repo defined as:
file://../local/path or file:///root/path

closes: #1884

fix(helm): add warnings for missing chart dependencies

feat(*): add --namespace flag to 'helm list'

docs(related): Add link to croc-hunter video

When 'helm install', 'helm package', and 'helm upgrade' are run,
Helm will not issue any warnings if any dependencies listed in
a chart's requirements.yaml file are missing.  This change includes
warnings when a chart is found in requirements.yaml but isn't
in charts/.

fix(helm): fix broken unit test

I recently added a test to check the sorting of search results.
Unfortunately, the test didn't actually sort the results (_sigh_), so
it was failing occasionally on map ordering.

This adds the sort function that is supposed to be tested.

Closes #1925

docs(helm): add doc to use `helm reset` to delete tiller deployment

Users can now specify a namespace filter for 'helm list'.  Only the
releases within the specified namespace will be shown.  For example,
'helm list --namespace foo' will only show releases for the 'foo'
namespace.  Also added a namespace field to the table view.
