Add optional quick face shortcut

[redraw]

This PR adds a simple way to quickly jump to a face from clock face.

This seems to be a different take on what I did in #104: the difference is that, there, the face that you jump to with the alarm button is not accessible through the normal Mode loop. In effect, long pressing the Alarm button starts a separate watch faces loop (separate from the primary and the secondary one).

On my build, I use that third loops for settings, tuning and other rarely used faces, so that I can use the secondary watch faces for more frequently used features (and the primary ones for the most frequently used).

Would that behavior work for your use case?

Oh nice. I actually like something simpler with this approach. I use the quick face as a separator between stock faces and custom ones. Since the alarm button in the clock face is unused, it could be assigned to various actions. I wonder if our use case matches someone else’s
