Android Lollipop 'Material' sound set
Every alarm, notification, ringtone, and ui that is default in Nexus devices running Lollipop is here. Due to some having 48k versions, all were listened to and the clearer, cleaner version was chosen to stay.

The commit also de-bloats the entire sound folder:
- Removed all of the KitKat and pre-KitKat sounds
- Removed all of the other sounds
