Captura el look de KDE (Layan): rc files, gtk theming, splash

kdeglobals/kwinrc/plasmarc/plasmashellrc/plasma-appletsrc/konsolerc/
dolphinrc/katerc/ksplashrc + gtk-3.0/4.0 settings.ini, capturados con
shared/capture-kde.sh de arch-setup. El tema Layan/Tela/cursores en sí
va por AUR (plasma6-themes-layan-git, tela-icon-theme,
layan-cursor-theme-git) en kde/setup.sh, no aquí; solo se vendoriza el
splash Animated-Abstract-Cube, que no tiene paquete AUR.
