Android ClassLoaderUtil cleanup;
- Add 'asset' URLConnection
- Please read API doc 'PiggybackURLConnection' and 'AssetURLConnection'
- Solves generic resource handling where platform locations may differ,
ie ClassLoader lookup on Android in the 'assets/' subfolder.
- New Android 'AssetDexClassLoader' uses 'assets/' folder for findResource(..)
- aapt.signed (our APK ant task)
- uses 'assets/' folder
- adds the 'assetsdir' attribute allowing to copy other assets into the APK
- IOUtil uses URLConnection / incr. effeciency
- using URLConnection on all getResource(..) since URL
is connected anyways for validation and URLConnection can be used by caller right away
- String getRelativeOf(URL, String) -> URL getRelativeOf(URL, String)
- preserves scheme, authority, etc
- simple parentOf handling, more efficient
- reusing new 'asset' protocol impl.
- Android ClassLoaderUtil cleanup;
- Use createClassLoader(..) impl for build-in static jogamp and user APKs,
which removes code redundancy
Tests: New code path, especially 'assets' are covered by new unit tests, no regressions on Linux.

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].
