Minor clean-up of consistency for tablet main menu styles
Added multilevel subnavigation in sidebar for internal pages
Updated search styling and positioning
Changed header color and link color to provide more consistency for the
theme
Footer links to red on hover and site name to link to homepage
Search results page styling updated
Moved some style declarations from layout to typography so that the cms
would pick them up.
Moved typography tag to the page.ss before layout is included
Changed typography elements to be wrapped in .typography, rather than a
layout tag within the Layout page templates. This will mean that a
bunch of modules have access to the correct type styling
