Merge branches 'doc_enhancements' and 'fixes_for_mainline' into improvements_for_mainline

* doc_enhancements:
  improved repo documentation
  Improved head and tag object documentation slightly
  Added docs for the error module
  Added missing information to docstrings of commit and stats module
  improved git.cmd documentation
  Improved documentation on Actor and Blob

* fixes_for_mainline:
  repo_tests: fixed duplicate test-method name which would redefine the previous one which never ran
  Fixed Diff class which used Commits instead of Blobs - as Blobs contain the path ( in the 'name' member variable ), the a|b_path members of Diff have been removed. Tests were adjusted and run
  git.git.Git.__init__ takes None as default argument as the execute method handles this correctly
  Fixed git.blob.Blob.blame function which would return the text-per-commit as individual characters
