[improvement suggestion] Autoshutdown on static settings

[Bullsquid]

I found out that the app is constantly running in the background, although I use it to just disable the lights on my GPU (animation type 5). Since the app only applies settings on restart, there is nothing more to do for it in modes 1 and 5. Therefore, I suggest to automatically exit the app after changing the LED values.

For now I've created a task in Task Scheduler to kill the app 2 minutes after login. I've set it to run Powershell.exe with the following arguments:

-command "Stop-Process -Name 'MSI LED Tool' -Force"
