untracked_files no longer detected #138

Hi,

The output of git status is no longer in the format expected by python-git, in
particular the Repo.untracked_files property parses the git status output
expecting a:

# Untracked files:

while later versions of git droped the #, also there are some subtleties in
the management of the file names (avoid the use of replace and rstrip
removes spaces not only '\n').

Here is a patch that fixes the untracked_files property. There might be other parts affected by the change in the git output.
