Raise awareness of the fact that some versions of swig and python (and
build types) just don't mix.
One day this will be a reason to require swig>=4.0, but this version is
too hot off the press right now..

This patch is a big sed to rename the following variables:
s/PYTHON_LIBRARIES/Python3_LIBRARIES/g
s/PYTHON_INCLUDE_DIRS/Python3_INCLUDE_DIRS/g
s/PYTHON_EXECUTABLE/Python3_EXECUTABLE/g
s/PYTHON_RPATH/Python3_RPATH/g
I've also renamed the CMake module to better express its purpose and for
consistency with FindLuaAndSwig.
