* Thanks for the reminder adam :)

This adds a few extra settings to the default .helmignore file. In
doing this, I found a bug that some directory patterns are not
evaluated correctly. Fixed that and added tests.

Closes #989
Closes #1027

This commit adds an Update function to the client.
The Update function takes in the modified manifests and
the original manifests. It then iterates through the modified
objects, creates objects not found in kubernetes, and updates
objects that exists but have been modified. Finally, it
iterates through the original resources and checks to see if
they have been deleted in the modified configuration and then
proceeds to delete them. #690

This changes "pkg/chartutil".Files.Get to return a string, removes
"pkg/chartutil".Files.GetString, and adds
"pkg/chartutil".Files.GetBytes.

Closes #1020

This adds a context-aware template function called 'partial' that will
allow rendering other templates in a chart into a string value, which
can then be piped to other functions. Usage is something like
'{{partial 'path/to/template.yaml' | indent 2}}'

This might be a bad idea.

Closes #1005

Templates can now access the non-template files in a chart by using
the '{{.Files}}' map inside of a template.

Relates to #950

This will allow helm install to re-use names for releases that were
already deleted.

I edited releaseMock as part of this PR
