Add an option to add a user-defined delay to the "start on boot" option.

I have a lot of programs that run auto-update packages on boot, but almost all of them won't update over the VPN, presumably because downloads through VPN IP addresses have been blocked.

Rather than running every updater through a split tunnel (which I would struggle to set up for every program) I would like to be able to delay the VPN startup on my PC.

I've done this presently with Task-Scheduler, but would be much more comfortable if it was in-app.
