Declares several CSS variables for styling buttons throughout the app and uses them. Removes the concept of a 'tertiary' button -- primary and secondary have the exact same styling, so all tertiary buttons are changed to secondary buttons and the existing secondary button (only replyBtn) is changed to a primary button. Also removes some of the many ways to modify a button color and background -- there is no need for mixins to specifically style various attributes of the paper-button when the ability to apply any styles directly to it (via @apply --gr-button) is already supported.
