Follow-up to the layer button order issue (Patreon)

Last week I asked for your help on a UI design decision with the GCODE viewer on devel I couldn't get mind made up on. Judging by the results you appear to have collectively been as ambivalent as me ;)

In the end I went with the slight majority here, with a small change to the wording on the buttons in question, turning "Layer down" into "Previous layer" and "Layer up" into "Next layer".

Considering the space restrictions in place that turned out better than my experiments to cram the buttons into the right bar or ordering the buttons vertically.

So for now, that's what we'll run with.

Thanks to everyone who participated in the poll and the discussion, it helped me a lot!
