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
Thanks.  I tweaked this to only wrap the callback() call, since we still want to retry even if there's no callback.
