extended easy taint wrapper to restrict its heuristics to classes in explicitly annotated packaged, e.g. "android.*" and "java.*". Otherwise, if the callee is not a phantom method and does have an active body, no taint is propagated via the wrapper, this must then be done by analyzing the callee. This should be more precise for most use cases.

Propagation of static taints along call-to-return edges is now also handled in the wrapper and not in the analysis itself which allows taint wrappers to drop static taints.
