2.0.2 Bump
Change release process to create binaries for upload

The previous release process involved isolating the master branch for
release purposes. This prevents seeing the commits between releases
and performing diffs on the source code.

The grunt "release" task has been updated to create .zip and .tar.gz
binaries that contain the built and minified for production use.

The initial medium for serving up these binaries will be GitHub, using
their new "GitHub Releases" feature that integrates with tags: https://github.com/blog/1547-release-your-software
