Feature Req: Title and App as separate fields

[Tycho-S]

I was wondering if it would be possible to make a separate field for sending app name and title. Right now we can choose to overwrite the title with the app name ("Force notification title to be app name") but I'd love to see both fields pushed to an2linuxserver at the same time.

This is probably not something necessary for desktop notifications, but I'm making a server to send the notifications to an MQTT topic instead. This way I can receive the notifications in more than one place. On the receiving end of that I would like to take different actions based on the sending app.

I know this won't be high on your radar but I thought I'd ask. I can't write a pull req for this as I don't have any experience writing android apps.
