Lateral change to add runtime "reprotection" at the python

side for protected director members.

Lib/python/director.swg: added needed code for runtime checking
Source/Modules/python.cxx: added needed code for runtime checking
director_protected_runme.py: checks now that the runtime protection is working


The extra runtime checking is only done for protected members,
so, the old public directors members don't feel any overhead.

This finished the director protected support for the python language.
Java and Ocalm will need to add the "reprotection" mechanism latter.
But as in the python case, the changes will be localized in the
languages files, and there will be no need to touch the core
files anymore.
