1.12.0 - Refactoring and consistency improvement

• Fixed partial so that :
  • when no argument is provided, it is equivalent to wraps(f)(f). That is, the __wrapped__ attribute is set. Fixed #73
  • it sets the func attribute just as functools.partial does. Fixed #75
• Removed pytest-cases dependency as it was a circular one. Fixed #68
• Now using flake8 for qualimetry and genbadge for badges. Fixed #71
• Restructured project so that tests are truly independent, to ease rpm/apt/etc. packaging. Fixed #69
