Subject: [PATCH 02/21] Gruntfile enhancements

* Use `git-contrib-copy` instead of `grunt.file.copy` paired with a
custom task.
* Build in `.tmp/build` instead of `gen`.
* Add `.tmp` to `.gitignore`.
* Remove `git-describe` config since that only applies when using the
`git-describe` module, not a custom task.
* Use `grunt.util.spawn` in `git-describe` task and nuke dependency to
`grunt-util-spawn` module.
* Break down grunt tasks into atomic tasks (`build`, `test:unit`,
`travis`, `default` and `release`).

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Add configuration for the following tasks:
  * `clean`: clean up `.tmp` and `dist`
  * `bump`: update `package.json`, `bower.json`, `grunt.config[‘pkg’]`,
commits changes, creates new version tag, pushes everything to
`GoogleChrome` remote
  * `changelog`:  Extracts release notes from changelog (changes since
last release), and adds a version header on top of the changelog.
  * `release`: builds, runs tests, updates dist bundle, bumps
`package.json` and `bower.json`, updates changelog, pushes everything
to git remote.
* Add `clean:all` dependency to `build` task.
