We have many styles related to the layout and visibility of search that are only useful in the context of the main header. Since many of these elements have classes that will also be in the sticky header, we should scope these rules to the main header so that we avoid an uphill battle of styles trying to override eachother. Additional changes: * We previously had a mix of #p-search and .vector-search-box selectors for the same element in the CSS. Header.less now only uses .vector-searchbox to avoid specificity wars. * Removed nearly all of the #p-search rules previously found on L147 - L167 in screen.less after observing nothing relatively bad happening when they were removed.
