Tab positioning

Temporarily fixed issue with the tabs wrapping down, when the browser zoom size(or text size?) is less than 100%.
(Temporary because we'd need to re-evaluate things using percentages or Em values)

Also updated the borders of the footer branding and player so the two sit within each other properly, instead of overlapping.
