Android: New ActivityLauncher (jogamp.android-launcher.apk)

ActivityLauncher provides delegating Activities, allowing the user to:

  - daisy chain custom APK classes and native libraries to the classpath

  - name one custom activity which gets delegated to, the downstream activity

Overview:

  [User:a1] -- (usr-data) --> [Launcher] -> [User:a2] + using [other packages..]

[User APK]   - The user provided APK
[JogAmp APK] - JogAmp APKs

[User:a1]    - The initial user activity, which starts the [Launcher].
               Providing data to [Launcher]: [User:a2], [User APK]
               Resides in [User APK]

[User:a2]    - The actual downstream 'real' activity, spoiled w/ full fledged ClassLoader
               having access to all packages as requested, ie. [User APK], ..
               Resides in [User APK]

[Launcher]   - The launcher activity.
               Gets called by [User:a1].
               Creates a new ClassLoader, daisy chainging all requested APKs.
               Instantiates [User:a2] w/ new ClassLoader.
               Delegates all calls to [User:a2].
               Resides in [JogAmp APK].
