python mapscript setup.py doesn't handle framework link options

[kyngchaos@…]

If a Mac OS X framework or framework path option are passed to setup.py, they are dropped because 
the setup script strips unknown options.  This patch did the trick for me:

Frameworks use the form: -framework foo, so are two words, thus the ex_next tracking.  Framework 
path flags are like library path flags, but with -F.  Distutils doesn't appear to know about frameworks, 
so I dump them all into extras.
