Added Activity from the Android SDK sample applications that allows to do
Bluetooth inquiring. This is needed because for some reason I couldn't launch
the included activity when doing a self contained APK, this also allows my
Python code to scan for more than one device, and run inquiring even though
I don't want to connect, or if I'm connected.
