This feature adds the ability to selectively control the loading of charts using entries in top chart's values.
When 'helm install --set tags.mytag=true', charts with that tag will be enabled unless disabled in parent by condition.
When 'helm install --set mychart.enabled=true', charts with that yaml path specified will be enabled.

This adds the {{.Capabilities}} object to the template variables so that
chart authors can write charts that are aware of teh Kubernetes
capabilities of the current cluster.

This fixes a bug in which passed-in values files were not correctly
merged into the chart's default values YAML data. I believe it also
fixes some other prioritization bugs in values merging.
The existing unit test was wrong (see TestCoalesceValues). It is
fixed now. Also added more tests to simulate issue #971.
In the course of writing this, I removed some vestigial code as
mentioned in #920.

This provides support for "global" variables. It does this by
declaring "global" to be a special namespace. It then copies this
namespace into every subchart, coalescing it into any "global"
namespace found there.
The net result is that if "global.foo" is set in the YAML file, it
will be available to every chart/subchart as ".global.foo" regardless of
where that chart is in the subchart tree.
