feat: Add setting to select start hidden or not

[zkmnnssm]

I have a little new idea now, I set RunMath to start on Windows start. but it just directly shows the window when I start my PC, and I actually don't need use it at this time，and then I have to press alt+m to hide it.

Finally added this. This won't be configurable as I think is the expected behaviour.

To fix this, make sure you have at least Runmath v1.15., then disable the autostart setting and enable it again (this should update the command that executes Runmath on Windows start).
