ADD: FindConsistentPython.cmake

     This adds FindConsistentPython.cmake to find Python libs and
     include directories consistent with the found interpreter.
     This has apparently been an issue for a long time and has
     been reported by many users.

     FindConsistentPython.cmake is an adaption from the Google
     code project:

     http://code.google.com/p/numexpr/

     where the authors have adjusted the original FindPythonLibs
     to accomplish the aforementioned task.
