Integrate AILS on Android

[korthout]

This has many complications:

• Felix on Android
• Felix Dependency Manager on Android
• Android is not JDK 8 compliant, so no more: java.time.Instant, java.util.Optional, Streams, Lambdas, etc.

AILS client code now works on Android. MainActivity starts Felix. Dependencies can be injected using Felix dependency manager. Which activators should be used (similar to bndrun file) can be added to the OSGiActivity.

In addition, Android now uses real access point measurements for its Wi-Fi profiles. These are displayed on the main activity.

Last but not least, we now use the INAETICS logo as app icon.
