Last minute 1.2 additions

Some small tweaks to get ready for 1.2.

[geoffrey-eisenbarth]

@dz4k two final things:

1. When I deprecated --rhythm, I actually used rlh bc I got the vibe that --rhythm should only be defined on :root. But, maybe it's better to replace those all with lh unit instead?
2. When I implemented colorways for buttons, I forgot that colorways kind of require explicit opt-in via .color and .bg. THe button impl doesn't require anything other than e.g. .ok / .info, etc. <select>, on the other hand allows for a toned down version with just .ok and a "fuller" version with .ok .bg .color. Is this inconsistency okay?

rlh is the right choice i think, because lh would scale with font size (e.g. on headings)

When I implemented colorways for buttons, I forgot that colorways kind of require explicit opt-in via .color and .bg. This is not the case for buttons (but, on the other hand, do require them to be "fully colorway'd". Is this inconsistency worth addressing in the css? I don't think there's anything wrong with that, .box also picks up colors automatically
