added bower.json

i added a bower.json file, cause component.json is deprecated.
there is also a problem with the github tag v0.0.11 and the component.json v0.0.10.
maybe u can delete the tag and push a new version:
git tag -d v0.0.11
git push origin :refs/tags/v0.0.11
after the merge
git tag v0.0.11
git push --tags v0.0.11
