bump: app version to 3.1.6

Added the ability to turn on and off tunnels via intents to the shortcut activity.

Added a setting to enable or disable shortcut/intent control of tunnels.

Added an experimental battery saver setting to auto-tunneling to fix the battery drain issue caused by wakelock.

Fixes a bug where sometimes the config screen could crash if there are issues parsing the tunnel config data.
