Added watch app settings menu

V1.4.1 introduces a settings menu for the GarminSD watch app - a long press of the Menu button on the watch (which one this is varies by watch model, sorry!) displays a menu. The main settings that can be selected are:

1. Notifications of alarm - select if the user is notified of an alarm condition by one of the following:
   Watch light switching on, Watch beeping, Watch Vibrating
2. Enable or disable Low Data Mode to reduce bluetooth traffic to attempt to save battery and improve reliability. (Note that this is not recommended because it does not send 3D data to the phone, which we expect to use in future seizure detection algorithms)
3. De-select the O2 saturation measurements to attempt to reduce battery consumption.
4. Enable 'Ben Mode' which is a mode where the timeouts for changing the app settings or exiting the app are very short, to make it difficult for users who like to fiddle with the watch to shutdown the app accidentally.
