kdereview: breeze-grub & breeze-plymouth

[Harald Sitter]

Salut!

As mentioned yesterday by Andreas Kainz, the VDG is working on a
unified design from boot to shutdown. To facilitate this we started
working on a GRUB and Plymouth theme that can now be found in
kdereview for your review pleasure.

GRUB is ready for review.
Plymouth is still in development as the design is not finalized.

It was suggested that we release both alongside Plasma so we can
easily enable distributions to brand coherent theme versions and don't
have to jump through git to find matching revisions of grub/plymouth
themes, hence the reviewing.
