Created restart-wg.sh file

Created wireguard restart script, which compares wg0.conf part between [Interface] and first peer with previous version for changes, and, if there is any - restarts whole wireguard, if the only changes are done to peers, it calls "wg syncconf", eliminating client disconnection after pressing apply config problem.
