Cleaned up repo and integrated with Travis CI

- Cleaned up package.json
- Cleaned up bower.json
- Added change log
- Added release.sh script to streamline release process
- Updated README
- Updated LICENSE
- Move spec files from `test/lib` to `test/specs`
- Got tests working from the command line via `grunt test` and `npm test`
- Got rid of checked-in dependencies and now load them via bower
- Added Travis CI integration
- Made fix for an integration test which failed when run via the command line
A trick I've used in the past is:

    npm install bower
    `npm bin`/bower install

But I don't see other projects doing that and I don't imagine that works on Windows...  so installing it globally is probably still the way to go.
