Ardutooth v1.3

Thanks to @grabinow2 a couple of new features have been added:

1. A method or two to read data from the Arduino. This makes debugging from the Arduino side easier.

2. A simple way to connect with paired devices. The method that establishes the connection with the Bluetooth device assumes that it is not yet paired (and if it is already paired the user would have to forget that device and re-pair with it).
