BtPromise: Adding a distinction between successful and failure.1.0
o Chain can now call fail() instead of stop() to signal failure. o The finally handlers can be changed to get this info later. o Should probably make all callbacks take the BtDevice as a callback instead of BluetoothGatt and make the gatt instance available through the device. This way state can be kept in the device's tag. BtPromise: always discover services when operating inside a connection.
