AndyActivity

Adding a killOnDestroy flag to kill the process when Activity is
Destroyed. This allows better kill option for extending classes

the contentView is set in this class itself. Extending classes must
implement and pass a View via createContentView(). Forces the extending
classes to pass something useful


AndyFace

passing Activity instead of AndyActivity since it is not compulsory for
developers to make their Activity extend AndyActivity. More freedom!
Hello Andy is the MasterApp which opens with a splash Screen and
showcases the basic modes of Andy Operations.
Adding an AndyWifiManager to manage the wifi connectivity functions
Adding the voice command mode
Adding Remote Control (TCP) and SpyMode. Still to work on the SpyMode
Adding icons and description on the mode list. Beautification basically
Revamped the entire AndyMotion API.

AndyMotion is now calling static. So no need of instances. Internal
AudioSerial is not using a separate thread since AndyMotion already uses
one.

Short tests show performance and reliability to be satisfactory

Also have implemented a way to identify zero speed and stop sending
audio data when speed is 0
