Add option to 'Additional Apps' to make Launchbox send it's details to LEDBlinky instead of the Parent app.

Currently, Launchbox sends the ‘parent’ game details to LEDBlinky when using the ‘additional apps’ feature. While i’m using it in a way it wasn’t strictly intended (prequels/sequels instead of versions), there are cases where that would still apply, i.e. different versions having an autofire button. It would be great if there was an override checkbox in the additional app edit screen to send the name of the additional app and not the parent app to LEDBlinky.
