Freestyle Python API improvements - part 9.

* Fix for wild card import statements (e.g., "from Freestyle import *") was done.
Now import statements are either without using "from" or with all imported names
explicitly listed.

* GNU GPL header blocks were added to Python programs.  Additional code clean-up
was also made.

* Removed freestyle_init.py and extra-lines.sml that were no longer used.
