Update gr-button to use paper button

Mostly styling updates but notable changes:
- Common color in theme.html, should be used by all buttons and links.
- CSS mixin to style gr-button passed to paper button (used in
  gr-label-score-row, gr-linked-chip)
- Some things that look like buttons but aren't exactly buttons get
  text-transform uppercase to appear like a button.
- Primary and secondary buttons are both the same color, but for now
- have not removed secondary so that it's possible to style them
  differently if we decide to.
