Retrieve all Hippo artifacts used as a dependency only through Hippo Nexus

Currently the channel manager frontend module uses Hippo components from github/onehippo directly retrieved (from github) by Bower.
For a tag or release these dependencies MUST only be retrieved from Hippo Nexus.
This also means these github/onehippo modules should be released and deployed to Nexus to begin with.
Preferrably this is also done continuously through a Jenkins Job for current SNAPSHOTs so there will be no need anymore to directly access (download) these from github.
Finally, to protect against accidentally using such SNAPSHOT dependencies for a tag or release, these dependencies might be first downloaded locally using Maven dependency:copy-dependencies plugin and from there 'downloaded' by Bower. This way, Maven becomes aware again of such dependencies including their possible SNAPSHOT status.
