"Add to Desktop" should mark launcher as trusted
It seems when whiskermenu copies a .desktop launcher to ~/Desktop it doesn't mark it as "trusted" according to Thunar, leading Thunar to show an "Untrusted application launcher" dialog on first launch. It would be convenient if whiskermenu could mark such items as trusted automatically.
This "trusted launcher" functionality was implemented in Thunar as part of Issue xfce/thunar#156 (closed)
Tested with whiskermenu 2.7.1 and Thunar 4.18.1 on Manjaro.
