Minor fixes; version bump;

- Travis CI's minimal node version was bumped to 0.7, as 0.6 didn't seem to work with dependencies;
- Version bumped to `0.0.3` in license comments and metadata;
- Added `bower.json` and `component.json`, and information about how to download through those in `README.md`;
- Added a bust (well, hopefully) to the Testling CI badge for GitHub.
