Add page level layout components

Adding components to help standardize type, size, spacing
for common elements on a page.

Also removed a conflicting class name and added modifications
to the main container. The main container needed a min-height
and height value set, which became apparent with added
background color. Adding a background color will move us
closer to agreed design solution to add a subtle background
color instead of adding a border to separate main content from
left hand navigation.
