Source Formatting: Move dockbar and base rules (980px min-width)

Reorganizing responsive rules to make it easier to maintain
Reorganized rules for Account and Add control list items

Before the properties for text color and text shadow and were specified in
two different media queries, but with the same values. So, they were moved
outside of the media queries so that changes only have to occur in one
place.
Bugfix: media query for the background of account and add controls

Previously, this property was in a media query, but was removed when it
was moved. It is necessary to restrict it, however, for larger widths when
the add controls in particular are displayed as icons instead of a
dropdown menu. Without the media query, the space between the icons was
being affected, which was not the intended affect.
Bugfix: Prevent navigation from having darker background (over 980px)

The background color was previously in a media query but was removed when
the rules were reorganized. This was a mistake and resulted in the
navigation and the dockbar receiving a background color at widths over
980px, making the navigation bar appear darker than all the other menus.
The rules need to be restricted to widths under 980px where the navigation
menu is a dropdown menu and does need to change its background on scroll.
