allow renaming of kde menu entry

If discord ist installed on linux with kde, it makes an entry in the kde menu. I can't rename or otherwise edit this entry as by default it is owned by root and is in /usr, with a symlink to that file in my home drive: ``lrwxrwxrwx 1 username username 34 Mar 13 07:44 /home/COMECH/craig.edwards/.local/share/applications/discord.desktop -> /usr/share/discord/discord.desktop`` i propose that instead this file be copied there by the installer, NOT symlinked, so that the user can rename it and edit it as they wish.
