Update grunt release task for new package structure

The task still creates .dist/node-red-xyz.zip as an archive
of the full release. It no longer creates .dist/node-red-xyz/ as
a directory containing the to-be-published module. Instead
npm publish should be run in each /packages/node_modules/**
directory in turn.
