Scope UX improvements

Go through the deliverables we got from the UX designers and break them out into issues. Put the low hanging fruit in the 0.8.0 milestone.

We have recently scoped the various UX improvements and broke them out into issues (see gui-v2 label). We also have an MVP issue, which suggests a path we can follow towards implementing most of the UX changes. It seems that the very first issues we can tackle are:

• GUI v2: Footer #886
• GUI v2: Welcome page #887

I wouldn't call those low-hanging fruits, but more like foundational issues, which happen to be small. We could add one of those in the 0.8.0 milestone, but I'm wondering if you want to make a pass before committing to a design.

Alternatively, would you like us to take a stab at issues like #889, without changing the visual identity of Dangerzone yet?
