Add the Neutrinet app and the Neutrinet app list to the cube install
In a previous version, we were tweaking the hypercube install script to install the Neutrinet app and the Neutrinet app list at the end of the Yunohost installation.
We should add them back, as the migration of the Neutrinet app is almost done.
We can use the new custom script feature (see #9 (closed)), this should make things easier.
