Bryan W. Weber b979cea3d2 Switch Cython and python interfaces to setuptools
Replace distutils with setuptools in the Cython and python_minimal
interfaces. Add console_scripts option to generate OS specific scripts to run
ck2cti, mixmaster, and ctml_writer

Remove script files that are obsoleted by console_scripts from
setuptools. Remove installation of the script modules from SConstruct.

Fix Python installers so that when a prefix directory is specified on the
command line, setuptools doesn't throw an error. The setuptools documentation at
[1] prefers setting PYTHONUSERBASE rather than PYTHONPATH. Use normpath to avoid
bugs in setuptools on Windows [2].  Specify an empty "--prefix" if the compiler
is clang to fix a bug with Homebrew Python on Mac OSX [3].
