Disable integration with Windows media keys

[jwhitten]

It seems Freda can be controlled by Windows Media Keys

I will look into it - media key integration in Windows is a bit of a tricky subject, but it should be possible to do something.  Probably it will need me to make code changes, and include them in a future release (I don't think there is a work-around you can use).

If you do change it, please make it selectable because I use the media keys. The only bad behavior is that the Read-Aloud playback stops (pauses) if you press a media key while in the Freda window. I can switch to a different window and can use the media keys just fine.
