A two-character pull request.

As a carryover from the days when we only allowed one source, the source
field was still labeled 'source' instead of 'sources'. Fixed and updated
all of the tests.

This fixes three things:
- #741 output is wrong
- #743 nil pointer error because of unchecked error
- Printing "Chart:" string in output

fix(helm): allow repo names in helm install

Now you can do 'helm install local/foo.0.1.0.tgz' and have the chart
installed from the repo, instead of just a local path.

fix(hapi): field for miscellaneous files

fix(helm): change TILLER_HOST to HELM_HOST
