Unit publishing and button sync up

This PR completes the Unit publishing widget styles (aside from synching up the colors with the WIP outline) and syncs up buttons page level/mast buttons across Studio. 

@talbs Can you review my work here? @cahrens Can you review (once tests pass) to make sure I didn't revert any recent changes?
Is this a change you want to make everywhere? The 'foo-button' classes are the ones that the UI drives from so that will require a lot of little changes. Hopefully we have good UI coverage for each of the buttons...
