Support for stack outputs (#581)
Adds support for top-level exports in the main script of a Pulumi Program to be captured as stack-level output properties.

This create a new `pulumi:pulumi:Stack` component as the root of the resource tree in all Pulumi programs.  That resources has properties for each top-level export in the Node.js script.

Running `pulumi stack` will display the current value of these outputs.
