sdlweb: Added mobile css code (media query).

From 73b20503c1c93f77b6ee1dc17aed53dd26950195 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Added mobile css code (media query). Removed most of the
 absolute px-values in CSS. Removed DejaVu, since it looks awful. Enhanced
 setLightTheme call (without flicker), which IS necessary on each page load to
 show users which one was loaded. Added burger-menu-toggle via JS. Added
 burger-menu CSS code. Removed round dot background imgage in the menus.
 Enlarged overall font-size and line-height since we are living in 2020.
