COMPASS-579: "Breadcrumb" Style Pass

[fredtruman]

• NOTE: Our link blue, used in the database and collection tables links is slightly off-putting when used aside our "compass blue" which is so dominant throughout the app. I would use "compass blue" for text links everywhere except it doesn't read well on white backgrounds. I think until we figure out a better palette using text links in regular linkText blue in our content areas and using "compass blue" for core navigation items is fine. Best shot.
• Put an overflow on collection titles
• Put cursors on any a:hover so non-hrefs will still get some affordance
• The collection header styles (stats and h1) have always kind of bothered me as they get pretty thin and crunchy, especially on non-retina screens. I bumped the weight up on everything here. The hierarchy feels much better to me this way.
