Preference page refactoring.

Broke down more CSS into individual files. Mild redesign of preference page to add glyphs in front of preference options and realigned toggles to look better. Took out random dividers in header menu.
Fixed officer page css issue on mobile.

Div tags were not closed breaking the mobile view.
Fixed about page menu styling.

Made the about menu full width and removed the terrible black background.
Fixed about contact page styling.

Foundation's small grid was pulling the twitter and email handle off the page on the mobile view.
