Currently, some assets are manually inserted into `vendor/assets` and not automatically updated, while others are added as gem files which do update automatically but require additional packaging work every time they change.
It would be beneficial to use bower to maintain those assets for the following reasons:

1. Reduce packaging work.
2. Allow more frequent updates of included assets, as updates will not require separate repackaging.
3. Allow simple updates to assets which don't have a gemified version.
4. Allow timely updates to assets who's gemified versions are not up to date.
