Fix Bug 583: Remove Android compile-time dependencies and exclude Android specific classes for non Android platforms.
Android specifics are delegated via class AndroidUtils, which uses reflection to call AndroidUtilsImpl if platform is Android. Android code is confined to the packages: jogamp.common.os.android.* jogamp.android.launcher.* and only included when compiled for the Android platform.
