Control the Windows Play/Pause Media Key with just the volume control on a headset.

Some headsets only have one control - volume.
This project supports using an up/down pattern on the volume control to trigger the Windows Play/Pause Media key.
For this to work, the headset's volume control needs to control the Windows volume, not just the volume of headset.

VolumeControl triggers a Play/Pause key press when the Windows volume is quickly changed first up, then down.
For a short time after the detection, any volume changes are ignored, and the volume is reset to what it was before triggering the Play/Pause key press.
The application will minimize to the system tray when closed via the X button, and can launch minimized and be started with Windows.

Max Delay specifies how quickly you need to changed the volume to detect the pattern.
Blind Spot specifies how long after a detection volume changes are ignored.
Min Volume Steps specifies how much the volume needs to change to be detected.
