Removed unused things, added some comments, added things to auto-sync wearable app to wearable, and other stuff.
Fixed wear manifest and now syncs watch faces. THE WORLD CAN REJOICE.
Updated the watch face to use Display Manager. Touched up the mobile side as well.
Updated files a bit to hopefully make them clearer. Also added release-signed apks.
