Merge branch 'feature/generic-wizard' into develop

The generic wizard (big) branch is now stabilised.
A bunch of refactors have gone together with this topic branch:

- client does not have any info included for default service providers.
- user has to run the first-run wizard and manually entry domain for sample provider.
- remove all remains of the older branding strategy for default provider.
- srp registration + authentication are integrated with the signup process.
