Icons instead of text for build results

[hennevogel]

@stanislav-brabec had the idea in #10705 to replace the text in the build-results on Project#show with icons to make the page less busy. Something like:

And move the full information to the hover then.

Could we go further? Since you can already collapse the repository, how about collapsing repository by default to just a header if there are a lot of repositories, and only show 4 ✔️ 5 ❌ etc for a distribution, which would mean 4 arches passing, 5 failing, which is expanded into listing of arches after pressing the header like in the current interface

It looks acceptable and easy to understand. But keep in mind, why we are doing that: We will be able to narrow the right column, giving more space to the main view.

@hellcp Sounds good.

Another possible improvement is an integration of "Last build results". I can imagine grey check mark for packages that succeeded before and now they are blocked/building/signing etc. and grey cross mark for packages that failed before.

Rationale: Both is important:

• The current build state is important for people who made a potentially breaking change and they are waiting for results.
• The last build result is important for people who want to know overall health of their project, even when Factory experiences a large rebuild.
