This is another set of tweaks to the sizes, units, and available design

tokens based on the work integrating Ink with Review Board:


More font size design tokens have been added.


New design tokens for input elements and headers have been added.


Spacing units are now smaller, based ona 0.8em base scale. This

  gives us some more reasonable sizes for "small", "medium", and

  "large". An "XXL" design token has also been added.


The button font size is now a bit larger, adding some emphasis to

  buttons and separating it from nearby text.


Header and footer border and text colors have been improved to better

  fit in with overridden colors (now using semi-transparent black/white

  borders).


Weak colors have been tweaked to use semi-transparent colors, and the

  weak text design token was renamed for consistency.

Tested in Review Board with some in-progress work. Verified that the

new styles gave us more control and better fit into the existing UI.
