rename : Cython/Tempita/__init__.py => Cython/Tempita/_tempita.py

simplify generated code by converting 'not X in Y' and 'not X is Y' into the equivalent not-in and is-not operators

extract normal cythonize script test from package compilation test as the latter is not supported in Py3.[012]

--HG--
rename : tests/build/cythonize_script.srctree => tests/build/cythonize_script_package.srctree

move cythonize script to Cython.Build.Cythonize to make it generally available and keep bin/cythonize only as a pure start script

Also added note to change log.
