Minor tweaks to CSS for better rendering:
 * Widen "appbrand" for times when font doesn't load
 * Fix position of cog in "preferences" menu
 * Switch to HTTPS for Google fonts (works with HTTPS sites, and extra security doesn't harm HTTP sites)
Make matching CSS changes to CSS (not source "less" file)
