Summary: Added Hidden=True nm-applet.desktop to xdg autostart so nm.applet doesn't autostart. This will be good since we plan to use network-manager-gnome for connection-editor but not for tray applet. Change default icon theme from papirus to ePapirus... which make dark icons gray instead of black so they look better in dark background Test Plan: See if icons change to ePapirus. See if nm-applet.desktop is present in ~.config/autostart with Hidden=true entry Reviewers: wxl, tsimonq2 Subscribers: apt-ghetto, hmollercl Differential Revision: https://phab.lubuntu.me/D11
