Show a notification on the top bar and play a sound.
The specified Title will appear on the bar initially. Notifications with a particular (non-empty) title replace existing ones with that title.
When the notification area is pulled down, the specified Text will be visible.
A Number other than 0 causes that number to be superimposed on the notification icon.
Music File specifies a file location on the sdcard e.g. music/hello.mp3. If it's blank, the default notification sound will play.
Up to 3 Actions can be specified which will appear in the notification area. In some cases it may be necessary to slide down to reveal the actions.
