V 0.1.3

This version adds notifications, a small vibration alerting you that the device you were trying to connect to has already connected to you, and the ability to save conversations to a .txt file. You can also copy the message you're currently viewing on screen by simply tapping on it (The NowiChat signing key was lost, so this is the latest version that is signed with the original signing key and the last one that should be installed or updated).
