Install update hooks so this repository gets updated when the component repos do #9
Description
Is your feature request related to a problem? Please describe.
Currently the submodule dependencies have to be updated manually. This is not so much a problem for the master branch as this will be a release step, but since we introduced the develop branch with regular updates of the submodule components, this has become a burden.
Describe the solution you'd like
Please implement a GitHub-based mechanism that updates the submodule relations once there was a push to the respective branch of a component repository.
Describe alternatives you've considered
Since we build the components using TravisCI, it might also be possible to trigger this from a component build.
