Moved functional_tests to subdir
mid Chapter 6 - changed functional/unit tests for /lists/ REST-style url adressing
Add *~ to not include vim backup files - removed existing backup files
chapter6: ft-/ut+: intermediate soln with 8 working unittests - working for /lists/the-only-list-in-the-world/ url
After refactoring: still -ft/+ut
[FT fails under windows - socket connection actively refused] ==> Seems to be a Windows thing with open/close of Firefo browser session
chapter6 intermediate: ft+(linux)/ut+ Added url,treatment,tests for /lists/new
Chapter6: Create lists (7 ut+)
chapter6: (10 ut+) Now can add item to existing list (with separate list management)
Chapter6: OK (10 ut) - Refactored urls.py: Now specify lists urls in lists/urls.py
