Significant improvement to album pages

Adds a two-column layout to the album pages, where the left column is
cover art and information and the right is the song listing. Also
commented on all the CSS classes/ids and fixed some little interface
issues (but also caused more, worry not!).
Styling fix

Made the margin between album info and the song list a bit thinner.
Jony Ive would be proud.
