[Ves] Configuring VES for Eclipse and ndk-build

[Sven Prevrhal]

When I added the KiwiNative.cpp and java files to my project and attempted
to build it, the 'dynamic_cast' in the vtk SharedPtr caused errors.

D:/packages/Android/android-ndk-r8c/sources/cxx-stl/gnu-libstdc++/4.6/include/tr1/shared_ptr.h:625:31:
error: 'dynamic_cast' not permitted with -fno-rtti

Reading up on android-ndk-r8c/docs/CPLUSPLUS-SUPPORT.html showed that adding

LOCAL_CPP_FEATURES += rtti

to my own module section in the Android.mk file would fix that - and it
did. I can now compile my app.

To actually make it run, I had to fix the bugs in Eigen's Visitor.h file
that Eclipse had flagged. Before fixing them, Eclipse would say "Your
project contains error(s), please fix them before running your application"
and cancel the launch.

One of the bugs is at Visitor.h line 37, around

  static inline void run(const Derived &mat, Visitor& visitor)
  {
    return visitor.init(mat.coeff(0, 0), 0, 0);
  }

is obviously a true bug, so removing "return" did the job here. At lines
194 and  228, the macro EIGEN_STATIC_ASSERT_VECTOR_ONLY has a definition
that uses the undefined
macro YOU_TRIED_CALLING_A_VECTOR_METHOD_ON_A_MATRIX, so i just commented
that out.

Now it launches.
