[rb-general] a logo for reproducible builds

[u]

Hi!

cool!

I like

#5  the black&white version
#11 because this is the most poetic idea
#12 because when we at Tails tried to explain RB to less tech-savvy
people, we ended up using the kitchen/baking metaphor:
https://tails.boum.org/news/reproducible_Tails/ and I'm pretty convinced
of explaining it like this.

Why I don't like the arrow images: it reminds me of the "recyclable"
icon:

Also, sorry it might be the German part of my brain, but #8 reminds me
of a swastika which is just missing its lateral bars.

Cheers!
Ulrike
